What is the main use of gas liquid chromatography (GLC) compared to gas solid chromatography (GSC)?
What is the main use of gas liquid chromatography (GLC) compared to gas solid chromatography (GSC)?
- Separation and analysis of polymers
- Separation and analysis of liquids
- Separation and analysis of solids
- Separation and analysis of gases (correct)
What leads to the separation of components in gas chromatography?
What leads to the separation of components in gas chromatography?
- Increased volatility causing rapid elution from the column
- Uniform migration of solutes due to similar affinities for the stationary phase
- Absence of migration due to lack of interaction with the stationary phase
- Differential migration of solutes due to different affinities for the stationary phase (correct)
