Question

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

Short answer

It's utilized to make volatile chemicals that the process can separate.

Step-by-step solution

Separate the gas.

It's a technique for separating volatile substances in gas chromatography.

The temperature incorporates a big impact on how well the compounds separate, hence the technique is employed to work out what temperature is best for separating volatile compounds with gas flow.

Adjusted the temperature.

Because certain samples contain compounds witha good range of boiling points at different temperatures, programmingis employed to change temperature (from lower to higher)so all compounds can evaporate and be separated bythe method.
