Question

What is meant by temperature programming in GC? Why is it frequently used?

Short answer

Temperature programming is used for component separation.

Step-by-step solution

Introduction

Temperature programming is a technique used in gas chromatography for sample separation. In the technique, the column temperature is changed multiple times from a lower point to a higher point in order to analyze new samples.

Uses

The method is used to optimize the separation. It can be used to solve great elution problems. By changing the temperature as it goes, the band broadening is minimized and the chromatogram gives good peak separation in a short period of time.
