The CHROMacademy Essential Guide Webcast:
Optimizing GC Detectors


Thursday 30th October 2014,
8:00am PDT / 11:00am EDT / 16:00 BST / 17:00 CEST

Join us to discover the working principles of a wide range of common GC detectors. We will examine the major variables which affect detector response and stability, as well as, discussing specific application examples. Many detector variables are ‘lock and leave’ parameters which are often overlooked; we will demonstrate that with a little optimization they can make a vast difference to your chromatographic method.

Understanding the working principles and optimization routines for the following detectors:

  • FID
  • NPD
  • ECD
  • TCD
  • Chemiluminescence
  • FPD
  • VUV
  • MS

Key Learning Objectives:

  • Understand the fundamental operating principles of GC detectors
  • Learn which parameters can be altered to optimize detector sensitivity
  • Learn how to choose the correct detector for your specific application

Who Should Attend:

  • Anyone working with GC
  • Anyone working with GC-MS

GC Detectors

This CHROMacademy e-Learning module details the working principles, optimization, and performance characteristics for a range of GC detectors which are commonly used.  The detectors covered include FID, NPD, ECD, TCD, and FPD.

GC Detectors - Characteristics (a) | GC Detectors - Characteristics (b) | FID - Operating and Optimizing |
The NPD – Operating and Optimizing | ECD - Operating and Optimizing

 
Fundamental GC-MS - Introduction

An introduction to fundamental GC-MS concepts.  The major components of the GC-MS instrument will be explained in detail; including coupling GC to MS systems, ionization processes, and mass analyzers.

Electron Impact (EI) | Chemical Ionisation (CI) | Mass Analyzers - Overview | Mass Analyzers - Quadrupole

Crimes Against GC Gas Filters

Are you guilty of any of our most commonly committed ‘crimes’ against GC gas filters?
These are probably the most common ‘crimes’ our technical team comes across in laboratories.

My GC Detector Flame Won’t Light

Although modern GC systems generally make lighting FID flames a straightforward exercise, if your basic settings aren’t correct you can still get significant problems.

Optimizing GC Detectors for Capillary GC

A fundamental guide to operating, optimizing, and troubleshooting common GC detectors.

GC Troubleshooting - Column & Detector Issues

The session includes a wealth of practical information on avoiding issues when preparing, installing and conditioning capillary GC columns. We also consider causes of capillary column aging and how to ensure your column remains fit for purpose for as long as possible. Also included is a quick revision on common GC Detectors (FID / TCD / ECD / NPD) as well as practical tips for avoiding problems and optimizing detector response.
We conclude by considering the symptoms of detector problems and building a list of troubleshooting and maintenance items which will be useful to the GC practitioner. Throughout, we consider both instrument and chromatographic symptoms. A must see for everyone working with GC instruments.

GC-MS Ionization Processes

The focus of this month’s Essential Guide webcast is GC-MS ionization processes.  The two main forms of ionization, Electron Ionization (EI) and Chemical Ionization (CI), will be discussed in depth.  The molecular reactions which occur within the ion source to produce ions will be examined along with which form of ionization should be used for particular analytes.  Finally, our speakers Dr. John Langley (Southampton University) and Scott Fletcher (Crawford Scientific) will impart some of their expert knowledge regarding optimization of the GC-MS process and some general interpretation strategies.
