Gas Chromatographs (AAS03)

This lesson introduces participants to gas chromatography and describes gas chromatograph principles.

Prerequisites

This lesson is designed for participants with an understanding of industrial process control, process analysis, and spectroscopic analysis. Participants should also have a basic understanding of chemistry and physics.

Description

This lesson introduces participants to gas chromatography and describes gas chromatograph principles of operation, components, and Applications appropriate for gas chromatographs are identified and discussed.

Objectives

Identify gas chromatograph system components. Identify the two most common types of columns: liquid on solid and active solid columns. Identify the components of a column switching system. Explain column efficiency-define resolution and peak interface. Explain the effects of oven temperature, sample size, and carrier gas flow on chromatograms. Explain the function of a programmer. Define each component of a standard chromatogram. Explain methods of determining column switching times for back-flushing. Describe how to program and calibrate a gas chromatograph. Be able to identify appropriate applications for using a gas chromatograph, such as butadine analysis and trace component analysis.
