What are the major components of gas chromatography?

A. Gas Source
B. Injector or sample application system
C. Chromatographic column (with oven for temperature control)
D. Detector and computer

Answer :

Final answer:

The major components of gas chromatography include the gas source, injector or sample application system, chromatographic column, and detector with a computer. These components work together to separate and analyze the components of a sample.

Explanation:

A gas chromatography (GC) system consists of several major components:

  1. Gas Source: This supplies the carrier gas used to carry the sample through the chromatographic column.
  2. Injector or Sample Application System: This is where the sample is introduced into the column. It can be a heated injector that rapidly volatilizes the components in a liquid sample.
  3. Chromatographic Column: This is where the separation of the sample's components takes place. The column is placed within an oven whose temperature can be controlled during the separation.
  4. Detector and Computer: The detector monitors the eluent as it comes off the column, and the computer records and analyzes the data.
