If you want to know how the pressure of a gas is control in chromatography then you need to read this post. You will get a piece of detailed knowledge about it. Electronic pressure control valves are quite commonly used these days to control air, gas, and fluid pressure but before we tell you how they can be used as an air pressure controller in chromatography we would like you to know what gas chromatography is about.
Gas chromatography is one of the most common use techniques for sensitive chemical analysis. You should understand that this kind of chemical analysis is suitable for all kinds of samples that can easily turn into gasses, which is why the process is also recognize as gas chromatography. The samples are use which are not only volatile but can also get stable when warm. You can take the example of residual solvents, blood samples, fatty acids, and others. Gas chromatography is also helpful in abuse analysis. An electronic pressure control instrument can help in all these experiments. There are many electronic air regulators which can help you without putting much effort.
What is the use of zero air in gas chromatography instruments?
Now you must know that zero air is commonly use in gas chromatography and the main purpose behind it is to give oxidants that can detect different results. You can take the example of FID which is also call as the flame ionization detector; it can easily detect the presence of hydrocarbons in a clean hydrogen sample. Now you must know that zero gas is no doubt very useful in chromatography when it comes to getting accurate results but at the same time, you must know that it is very important that you control the pressure of zero gas as it can do a lot of damage if leaked. Today you can use the modern electronic pressure control tools for this purpose. The air pressure control valves in the digital regulator can help you control the zero gas pressure and supply automatically. This can decrease the chances of any losses or risks.
How does gas chromatography work?
Gas chromatography might be a new concept for most of you but you must know that it is very important to know how it works. GC aka gas chromatography works on a simple principle. A mixture of compounds is separate in a long class coat tube. The column of the tube is internally coat with a stationary phase and also with the substrate. The interaction of molecules in the mobile gas and stationary can separate the compounds on the basis of their physical and chemical properties. To avoid any losses and chemical disruption electronic pressure controls are used so that there is no way there is any loss in the substrate or the testing material. For accuracy, it is important that the modern proportional air regulators are used.
What are the benefits of zero air generators?
Today the majority of analytical labs are using zero air generators. There are many benefits of this gas some of which have been discuss below:
- First, you should know that you can enjoy cost reduction. You can end up wasting a lot of money on manually maintaining air pressure.
- There is a very low risk of loss in handling or delivery of samples especially when they are in high pressure cylinders. The electronic air pressure regulators can ensure low risk at a low cost!
- There is no risk of running out of gas or substances when you are using the electronic pressure control.
- Digital regulators in gas generators are low maintenance and labor-friendly!
