Basic GC Instrumentation

Course Details Premier

This learning path on basic GC instrumentation covers system setup, gas supply management, and pressure control. It includes sample introduction techniques, autosampler configuration, and detector optimization (FID, ECD, TCD, MS). Practical strategies focus on instrument setup, maintenance, and troubleshooting for reliable, high-performance gas chromatographic analysis.

Practical GC Video Bootcamp
Module

Practical GC Video Bootcamp

A step by step guide to setting up a GC instrument. From checking the cylinders, dismantling the inlet, to correctly installing a column and lighting an FID. All before shutting the instrument down correctly. This practical module uses video filmed on a GC instrument in the lab to ensure that you get the most realistic walk through of the instrument; allowing you to correctly setup your instrument every time to get the most from it and decrease down-time by avoiding common mistakes. 

Gas Supply and Pressure Control
Module

Gas Supply and Pressure Control

The aims of this module include outlining the nature and quality of the gases required for GC analysis, as well as highlighting the various methods for controlling gas pressure and cleanliness including troubleshooting strategies. The use of gas generators as a viable alternative to cylinders for GC gas supply will be discussed. The principles of manual and electronic pressure control for GC carrier, inlet, and detector gas regulation are described as well as the differences between constant pressure and constant flow experiments.

GC Sample Introduction
Module

GC Sample Introduction

The aims of this module are to outline the various injector categories for GC as well as describe the components and working principle of split and splitless injectors. We will look at problems associated with each of these injection types and explain how they are overcome practically and give examples of optimizing inlet parameters. The working principles, components, and optimization for a series of common GC inlets are explained, and choices for inlet consumables are also discussed.

GC Autosampler Setup
Quick Guide

GC Autosampler Setup

Over four short videos we will look at how to correctly setup a GC autosampler. We will consider parameters that can be changed by the user, including the syringe and needle, needle wash routines, vials, injection speed, viscosity delay, and dwell time.

GC Detectors
Module

GC Detectors

The aim of this module is to highlight the various detector types available for GC and describe the performance characteristics associated with these detectors. The working principles behind flame ionization, electron capture, nitrogen phosphorous, thermal conductivity, and flame photometric detectors (FID, ECD, NPD, TCD, and FPD, respectively) are explained, as well as the optimization process for each of the detector types.
