Question

In gas chromatography, the basis for separation of the components of the volatile material is the difference in :

• A. partition coefficients
• B. conductivity
• C. molecular weight
• D. molarity

Answer 1

The correct option is A partition coefficients

The basis for separation of the components of the volatile material is the difference in the partition coefficient of the components as they are carried through the column by an inert gas such as helium.
