Understanding PID Analyzers in detail

The full form of PID is photoionization detector. PID analyzers are gas chromatographs with a photoionization detector which is basically used for multi-gas analysis. Volatile organic compounds are best detected by the photoionization technique. The sensitivity quotient is very high in this technique and is able to provide both manual and automatic analysis. The molecules of the sample are broken into positively charges ions by high-energy photons which belong to the vacuum ultraviolet range. Subsequently, an electric current is produced which gives output to the detector. The amount of current depends upon the concentration of the substance. The PID analyzers were introduced in the application of gas chromatography in 1976.

Salient Features of PID Analyzers

The main features of these instruments are that they have low maintenance time and perform at lengths; it has less moving parts and has electronics which have high durability, and there have high reliability and stability factor and have ability to operate under ambient air pressures. The biggest benefit of the usage of gas chromatography with PID analyzers is that the matrix effect is at its minimum as the analyte goes into the detector without compounds that have the ability to interfere with the results. We have to keep in mind that when we are working in environments or conditions with high humidity or when methane or methane-like compounds are present the signal produced by PID will be quenched. The ion current is drastically reduced as ionization energies are absorbed by water and methane as they absorb photons emitted by the UV lamps. Resultantly energetic photons for ionizing the analyte are reduced. The main thing to remember is that the sample gas is not burned or changed as gas ions recombine to form the original vapor. As an individual organic compound has its own threshold energy of light it is easy to use to sense by PID. Noble gas and a window material with a photon energy source are the main components of the PID lamps which are used to create photo ions. Argon, Krypton, Helium, and Xenon are mainly used. Lamps with high output, longest life are mainly advisable and give response to a maximum number of compounds.

A device which supports it thoroughly

Another very important device used in gas chromatography is the GC Zero Air generator. We have to first understand of the concept of Zero gas and its necessity. As a layman, you can say that is sterilized, clean, pollutant-free, humidity-free air. As there are technically less than 0.05ppm of hydrocarbons in the Zero air. Also, compounds or gases generally present in the normal air like Sulphur dioxide, carbon dioxide, and carbon monoxide are also absent in zero air. As the hydrocarbons and other impurities are drastically reduced in zero air and thus the detectors are able to give the best results with better baseline stability and background noise levels are also reduced. You can get zero air also in cylinders but is preferable to get an onsite GC Zero air generator due to points mentioned in subsequent lines. Delivery costs are nil, cylinder rental charges are non-existent. You are sure of purity on zero gas produced onsite and your investment is returned within one year of purchase.

Understanding the significance of the GC Capillary Column

Capillary Gas chromatography (GC) is a simple insulating device with a narrow tube with an insulation coating in its interior side.

Overall there are three types of capillary Gas cylinder available in the market which can be used for this purpose. They generally have tube -like structure and are differentiated on the basis of their coating; they are wall coated, support coated and porous coated.

Wall coated or WCOT are open tube chambers.
Support coated or SCOT are open coated tubes having liquid in it.
Porous coated or PLOT are open coated tubes having poros absorbent.

Characteristics of capillary Gas chromatography are:

They are used in GC.
They can provide high resolution
They are capable of low sample capillary.
They have shorter analysis time.
Flow rate goes to 10-20ml/min in packed chambers
Flow rate goes to 0.5- 2ml/min in capillary.

What is chromatography?

Gas Chromatography Column is just a simple process of sorting compounds which are generated due to the striking of solid surface to mobile surface. For instance if you take water or alcohol and throw it on a paper it will move on it. But what you will observe is that the rate at which it is moving directly depends on how heavy or sticky are the compounds of the flowing substance. If it is heavy it will flow slowly or sticky it will flow slowly but if they are lighter then the situation will definitely go vice versa.

This situation can differ in gases as Gases are the mobile substance and can move where they want.

How does the movement take place inside the capillary column?

In the capillary column the gases move inside the column due to the presence of high pressure between the inlet and Outlet.

However the speed of this can totally vary as it is based on how quickly and speedy they have traveled as mentioned above the rate at which it is moving directly depends on how heavy or sticky are the compounds of the flowing substance. If it is heavy it will flow slowly or sticky it will flow slowly but if they are lighter then the situation will definitely go vice versa.

One thing which needs to be noted according to experts is that it doesn’t contain coated particles and if we are trying to do so then it can result in forever blockages. Coating is always done into the interior side of the chamber

What are the dimensions of capillary?

Capillary columns are narrow tubes which can vary from 12m to 60m in length and can have internal variations as well.

But in general their dimensions are from 30m -60m in length x 0.24 um ID x 0.25 um film thickness.

However, the ideal thickness for capillary is from 0.1 mm to 0.53 mm. These columns give much seperate as company to packed ones.

The necessity of Hydrogen Gas Cylinders in Gas Chromatography

There is a basic need for different gas supplements and other equipment for laboratory purposes. When we are discussing gas chromatography there is an acute need for using such supplements for better use. At different times people are not able to take the need for a more efficient form of supplements which can provide them better adaptability for a very long time. In this module, we are further going to put some light upon the usage of hydrogen gas generators and also the use of hydrogen gas in the process of gas chromatography.

There are different alternatives available for hydrogen gas generators due to which people refrain from using the same option. But there are different folded and concealed side effects of using the other alternative which can be overthrown with the help of a hydrogen gas generator easily.

What is the real problem with the using alternative options?

As you might already have noticed that there are different alternative options available but not all of them manufacture or generate hydrogen gas for gas chromatography or other purposes. Different industries and other manufacturing firms take the necessity advantage of hydrogen gas for different purposes. Whether it is due to its lightweight characteristic or inflammable capacity there is always an active need for hydrogen gas in analytical chemistry. Most of the alternative options provide a much safer way of storing hydrogen gas in tanks or other hollow spaces. But there are different disadvantages due to the same.

A higher rate of contamination of hydrogen gas over time is among one of the firsts. The molecules of any gas are loosely packed and can travel even through the shortest space. Hence, the probability of contamination from other gases is quite high. Furthermore, hydrogen gas is quite inflammable in nature. Any sort of leakage can be quite dangerous for the workplace.

How hydrogen gas cylinders provide better efficiency?

As we have noted down different advantages of using other alternative options hydrogen gas generators can provide a better efficiency above all of them. There are minimum drawbacks available with the use of the same. Hydrogen gas generators do not rely upon the system of storing hydrogen gas for a long period of time. It generators Nitrogen gas directly which are also quite purified in nature. Pure hydrogen gas with minimum contamination can provide a better result along with accuracy.

People are likely to think that using certain equipments can add the cost but it actually the settlement cost of the complete generator is costly but it can provide a better sort of money efficiency after the tedious task is done.

Why using PID Analyzers to become Quite Acute?

One of the most crucial equipment with people generally use for the complete gas chromatography process is PID analyses. Apart from just the gas chromatography process, there is an active need for PID analyses for various different purposes. The actual gas chromatography industry is widely elaborated and large and there is a need for various different things in the same industry. Various different processes are used side by side to provide better efficiency to the people. PID analyzers are among one of the things that you have actually come across various different times even in various different fields. One of the best things along with PID analyzers is that apart from this gas chromatography industry they provide various efficiencies to a very large extent. PID is an acronym for Photoionization detection analysis.

As the name already suggests itself on monitoring different volatile organic compounds which can quite be dangerous if they are present in the surrounding working area. Being quite inflammable and destructive there is a need to monitor them regularly and for the same process PID analyzers are widely used. Use of PID analyzers is acute actually for the safety purposes. It becomes quite acute for preventing the chances of accidents in the complete environment. There are various different fields which generally use different volatile organic substances and enhance the use of analyses become quite acute in certain fields.

PID analysis gas chromatography

Gas chromatography specifically takes the assistance of PID analyzers because it becomes quite essential for the complete process. As you already know gas chromatography take the assistance of various different sort of gases and most of them are quite inflammable and there monitoring is a must. Any sort of liquid can be quite dangerous for the complete work place of the chromatography industry.

To provide much better assistance, gas chromatography generally installs PID analyzers in their workplaces. Hydrogen gas generators specifically generate hydrogen gas which is quite inflammable. Their assistance with the same can be effectively dangerous for everyone. Nitrogen gas generator actually mitigates the risk of leakage of any hydrogen gas in the environment but the probability is not absolutely zero. Nowadays there are various different pharmaceutical companies that are also using PID analyzers to keep a check on the safety of their working environment.

Other sectors where the use of PID analyses are efficient

Actually, there are various different similar sectors that take the assistance of PID analyzers due to their efficiency. From the pharmaceutical sector of the gas chromatography, there is an acute need for all of them. One thing that we take into consideration commonly is that each and every sector which are dealing with the process of analytical chemistry takes the assistance of PID analyzers for the process of efficiency. Day-by-day workplace accidents are increasing due to a lack of much concern on leakage of volatile compounds So there is an active need for taking certain precautions to avoid any sort of leakage.

There are various different environmental forms that are also using PID analyzers to get to know about the contamination of different volatile compounds in the surrounding environment. Actually using PID analyzers is not something that is quiet sophisticated or complex. There are various different sort of real analysis which IS actually available and anyone can use it without any sort of prior experience. There are certain residents which also use PID analyzers on their homes just for the purpose of safety.

What is a Flame Photometric Detector for Gas Chromatography?

When it comes to the flame photometric detector for GC, it actually means that it is a technique widely accessible in the gas chromatography industry. This is also the actual use and purpose of this particular technique. This particular technique is to analyze the content of sulfur, Phosphorus element, and other certain metals including Boron, arsenic, and chromium. For most of the purposes, particular hydrogen equipment is equipped which is further used by an FPD. Chemiluminescence is present in Phosphorus and sulfur element in some specific wavelength which can actually be passed through different photomultiplier produces some sort of electric signal. The study actually includes measuring device type of signals to a large extent it is actually one of the main functions of the flame photometric detector for GC.

Do you know the Difference between PID and FID?

PID analyzer is a photoionization gas detector. It is used to measure the concentration of the ionized particles. Besides that, it is also used to measure the concentration of volatile organic substances. It simply measures the concentration from the sub-parts billions to 10000 parts per million. This equipment generally releases the photons and these photons are absorbed by the ionization chamber. In a PID Analyzer, you get an immediate result, so you can easily and quickly note the readings.

What technology is used by the PID Analyzer?

PID Analyzer uses the Gas chromatography column supplier technology. This technology is generally used for gas separation in this equipment. In all this process one phase remains fixed on the other hand the second phase is a mobile phase, which is a carrier gas. This mobile phase flows over the stationary phase. The compounds with the lower vapor pressure remain stationary for a longer time.

There are two factors on which it depends for how long a compound can be in a stationary phase:

1. The first one is the compound’s vapor pressure

2. And the second one is “what is its solubility in the stationary phase?”

Understanding the role of Nitrogen Generators in Chromatography

Nitrogen generators are widely used in various sectors related to chromatography. Nitrogen generators are used in chromatography where a stable and continuous requirement of nitrogen supply is necessary. LC-MS nitrogen generators and nitrogen generators as gas chromatographs are widely applied in chromatography.

LC-MS is an acronym for Liquid Chromatography-Mass Spectrometry. It is an analytical chemistry technique used widely to determine the various different constituents of complex mixtures of certain chemicals and other effluents. The technique is generally used and found in analytically advanced science laboratories. For the proper functioning of the LC-MS system there is an acute need for LC-MS nitrogen generators. The nitrogen supply can be static, in other terms stored particularly in big cylinders and tanks or can be dynamically generated on the laboratory itself.

Importance of purity of nitrogen used for LC-MS

The purity of nitrogen is the thing that needs the most concern. About 95% of the purity in the nitrogen gas is recommended. The remaining 5% is the oxygen gas which has not been found during the time of analysis through generators. Manufacturing companies need to take the concern of using only high-quality materials while manufacturing. The nitrogen generators used as gas chromatography and LC-MS equipment are generally manufactured by materials which are Phthalate and Butylated hydroxytoluene (BHT).

Phthalate and BHT can have a powerfully negative effect on the quality of Oxygen gas which composes about 5% of total air.

How do nitrogen generators help in lab workflows?

Having a nitrogen generator as a gas chromatograph in laboratories provides significant ease in the overall functioning of the laboratory. There is no need for the workers to monitor and check the gas cylinder’s level again and again. It also eliminates any unwanted disruption between the analyses. The gas can be generated on the demand of the laboratory. LC-MS nitrogen generators ensure the availability of gas in the lab all the time, eliminating any supply issues and delays of nitrogen gas cylinders.

Replacing nitrogen gas cylinders with LC-MS nitrogen gas cylinders is economically feasible for the laboratory. A typical LC-MS requires about 10,000 Liters of nitrogen per day. It is an alarming quantity. It consumes about one cylinder every day for laboratory use. LC-MS nitrogen generators are much feasible economically for laboratory use. You can alter the generation rate of Nitrogen gas through nitrogen gas generators.

Why do nitrogen generators give consistent results?

Nitrogen generators can provide more consistent results for analysis. The case of gas cylinders is not that they are always impure and will not have any accurate results but the quantity and quality of gas vary largely. They need to be changed certainly and this transition introduces impurities in the analytical system. Such impurities can provide widely inaccurate results for a certain experiment.

Nitrogen generators are much safer

Nitrogen generators are much safer gas chromatographs. Nitrogen gas can create an asphyxiating environment. To avoid such accidents there is a particular need to use supplements that eliminate the chances of leakage in the site.

It is obvious that gas compressed on cylinders at high pressure may cause leaking hazards and lead to certain unwanted accidents. Nitrogen generators on the other hand can be used for optimizing the concentration and generation of nitrogen gas and hence they are widely adopted by lots of consumers worldwide for various applications including laboratory operations.

Nitrogen generators are much safer for the environment. One by the use of nitrogen generators can help in protecting environment degradation.

Do you know these things about the Gas Chromatography?

Gas chromatography is a type of column chromatography which is used to separate the volatile organic compounds. In this, the solid phase can be any inert gas like nitrogen, helium, and hydrogen and the stationary phase can be any liquid or solid. This process is widely used in so many industrial, pharmaceutical and other significant areas. Let us check out some important facts about it.

What are the different types of gas chromatography?

There are two types of gas chromatography:

GSC: In this type, the packed column is filled with the solid sorbent.
GLC: In this type, a thin liquid layer is used.

What are gas chromatography columns?

Let us understand the physics behind the gas chromatography columns. These columns are used to separate the identical elements of the gases without the decomposition. In this process, the sample gas is injected into the gas chromatography columnsand then separated in another column in the stationary phase. After the separation process, the sample of the separated gas is identified in the detector. In this, all process the separation of the gases is done by the interactions taken place in between the volatile analytes and the stationary phase. There are two major types of columns used in gas chromatography. These are packed column and capillary columns.
