What are the main characteristics of the mobile and stationary phases in gas chromatography?
What are the main characteristics of the mobile and stationary phases in gas chromatography?
Homework Answers
Solution :
The main characteristics of mobile and stationary phases in gas chromatography are given below.
>> The mobile phase in gas chromatography must be interactive, mainly comprised of an inert gas. i.e., helium, argon, or nitrogen.
>> The stationary phase in gas chromatography consists of a packed column in which the packing or solid support itself acts as stationary phase.
>> Stationary phase plays a vital role in determining the selectivity and retention of solutes in a mixture.
