Question

What is meant by temperature programming in gas chromatography?

Temperature programming involves increasing the temperature of a GC column as a function of time.

Temperature programming is usually applied to samples containing a mixture of components that have boiling points within a narrow range.

Temperature programming keeps the temperature of a GC column at a fixed value as the separation proceeds.

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

Explanation / Answer

Temperature programming in gas chromatography means temperature programming increases the elution time and the time required to complete an analysis.

Temperature programming in gas chromatography is so much important because change in temperature affects not only retention but also relative retention in gas chromatography (GC) and t by changing temperature, the selectivity of the separation can be changed.
