Gas chromatography is an analytical chemistry technique used to identify and quantitate the compounds in a mixture that can be vaporized without decomposing. The simplicity and sensitivity of this method means that it is widely used for applications such as drug testing, analyzing essential oils, and breaking down food samples.

6 Questions to Ask When Buying a Gas Chromatography System:

  1. What columns will you need for your sample type?
  2. What detector (FID, MS, TCD, etc.) is best suited for your application? Will you be pairing gas chromatography with mass spectrometry?
  3. What is your throughput? Would an autosampler improve your efficiency?
  4. How easy is the system to use and what analytical software is available?
  5. Would a used gas chromatography system be a better fit for your budget?
  6. What eluent gas do you need? Have you considered using hydrogen?

Addressing the Helium Shortage

With the fourth helium shortage in 20 years upon us, it may be difficult to replenish your lab’s supply for the foreseeable future. To continue your research during the shortage, you can try alternative carrier gases like hydrogen or nitrogen, which can be supplied on demand with a gas generator.
