Gas chromatography (GC) separates a mixture of chemicals (a sample) into individual components. These components (or analytes) can then be analyzed for their identity and their concentration in the sample. In general, analytes must be volatile or semivolatile (able to be vaporized) in order to be anlyzed on the GC. Analytes must also be dissolved in an organic solvent at very low concentrations.
The uses for GC are numerous. They are used extensively in the medical, pharmacological, environmental, and law enforcement fields. SRIF has the following GC equipment.
