The CHROMacademy Essential Guide Webcast:
GC Gas Control and Sample Introduction

Thursday 25th May 2017,
8:00am PST/ 11:00am EST/ 4:00pm BST/ 5:00pm CEST

   
 
 
 

Get the most out of your GC by understanding how it works. 
This webcast will look at how gases are delivered to the instrument and detector, the importance of gas cleanliness, the effect of different flow modes, and how the most common inlets function.

Presented by John V. Hinshaw (Senior Scientist, Serveron Corporation)

Tony Taylor (Technical Director, Crawford Scientific)

Topics Covered

The importance of GC gases and sample introduction for successful chromatography

  • Ensure your GC gases are fit for purpose
  • Electronic pressure control of gas flows to the inlet, column, and detector
  • Constant pressure and constant flow modes
  • Principles of split, splitless, large volume and headspace sample introduction

GC Gas Control and Sample Introduction - Tutorial

This month’s webcast focused on GC gas control and sample introduction.  The CHROMacademy material provided in this month’s tutorial will give you further insight into the practical aspects associated with the components used in a GC instrument to control gas flows and introduce the sample for analysis; such as, gas cleanliness, flow programming, and inlet optimization.

Our Quick guides, CHROMacademy course content, and archived webcasts and tutorials will provide the information required to get the most out of your GC by understanding how it works.

10 Things You Didn’t Know About Your GC

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.
