2022 Helium Shortage and How to Use Hydrogen Instead as Your Gas Chromatography Carrier Gas

Have you heard about the helium shortage in 2022? Well if you haven't you're about to find out about it the next time you try to buy some helium. There's a helium shortage in the world and there's a sort of a complex discussion as to why.
Chromatography Applications In Pharmaceuticals

Chromatography Applications In Pharmaceuticals

Pharmaceutical industry is huge in chromatography because in that industry they must by law analyze their raw materials to prove that there's nothing bad in it.
Does Water Show Up In Gas Chromatography?

Does Water Show Up In Gas Chromatography?

So let me answer this a couple different ways. First of all, in a GC our predominant detector, our main detector is the FID, flame ionization detector. The FID cannot see water.
How Do You Improve Resolution In Gas Chromatography?

How Do You Improve Resolution In Gas Chromatography?

That is a great question because resolution means the spacing between the peaks. Remember chromatography is a separation tool. If we can't separate then we don't go on to step two.
Chromatography Applications In Forensics

Chromatography Applications In Forensics

Imagine that you are watching CSI, and the lab technicians run a sample by GC-MS or HPLC in order to get the answer and catch the bad guy. That is an example of a chromatography application in forensics.
