Event Overview

Gas chromatography (GC) is widely used in variety of application areas, yet rarely is the application or equipment properly optimized. With nearly 70 years of use since its invention in 1947, much is known about the technique, however, there is always room for everyone to sharpen their practice, so we’ve put together 10 of our favorite lesser known facts which we think will have a positive impact on your GC data.

Topics Covered:

  • Split vent trap - GC’s dirty secret
  • Why hydrogen is the best carrier gas
  • Generators vs. cylinders - who is the champion of safety?
  • The benefit of using a GC-MS designated column even when you don’t do GC-MS
  • Advantages of ultra-inert columns
  • Guard column or retention gap - what’s the difference and when to use them
  • A little bit of split can give you better peak shape
  • The wonder of gas saver mode
  • Where does your GC measure the flow out of the column?
  • How important is it to know the correct column length?
