Question

What is meant by temperature programming in gas chromatography? Temperature programming keeps the temperature of a GC column at a fixed value as the separation proceeds. Temperature programming is usually applied to samples containing a mixture of components that have boiling points within a narrow range. Temperature programming increases the elution time and the time required to complete an analysis. Temperature programming involves increasing the temperature of a GC column as a function of time.

Explanation / Answer

Temperature of programming increases the elution time and the time required to complete analysis.

The temperature of column is raised during the seperation to increase analyte vapour pressure.
