Gas Chromatography

4.0 1 Review SKU: LTGAS00CENDuration: 60 Minutes

This course explains how sample components can be separated by gas chromatography. It discusses the basic principles of the gas chromatography process and describes the major parts of a typical gas chromatography system, including an auto sampler, packed columns, capillary columns, a flame ionization detector (FID), and a data system. It describes the major steps of a chromatographic analysis, including sample preparation and injection, sample separation, component detection, and data processing. It also discusses the basic features of a typical gas chromatogram and describes how the information presented on a gas chromatogram is used for qualitative and quantitative analysis.

Learning Objectives

  • Define the following terms: "chromatograph," "chromatogram," "mobile phase," "carrier gas," "stationary phase," "gas-liquid chromatography," and "gas-solid chromatography."
  • State the three main goals of gas chromatography in most cases.
  • Explain how components are separated and analyzed by gas chromatography.
  • Describe the function and features of a typical carrier gas supply.
  • Describe one way to prepare a liquid sample for injection.
  • Describe the basic operation of an auto sampler.
  • Describe the function and features of a typical injector for a gas chromatograph.
  • Define the following terms: "resolution," "HETP," "sample capacity," "packed column," "capillary column," "selectivity," "retention time," "tailing," "isothermal operation," and "temperature programming."
  • Describe the function and features of the column and the oven for a typical gas chromatograph.
  • Describe the following types of chromatography columns: FSOT, WCOT, PLOT, and SCOT.
  • Define the following terms: "sensitivity," "minimum detectable level (MDL)," and "peak integration."
  • Describe the basic features and operation of a flame ionization detector.
  • State the functions that are typically performed by a microprocessor-controlled data system.
  • Identify the basic features of a typical chromatogram and describe how the information on a chromatogram is used for qualitative and quantitative analyses.
  • Describe the ideal appearance of a chromatographic baseline and identify common types of baseline abnormalities.
  • Describe the ideal appearance of a peak on a chromatogram and identify common peak shape abnormalities.
