What is the purpose of preparative chromatography?
What is the purpose of preparative chromatography?
- To separate components for further use or study (correct)
- To identify the constituents of the mixture
- To analyze the interactions of the mobile and stationary phases
- To determine the partition coefficient of the mixture
What is the role of the mobile phase in chromatography?
What is the role of the mobile phase in chromatography?
- Interacting with the stationary phase
- Carrying the mixture through the system (correct)
- Causing differential partitioning
- Determining the retention time of the constituents
How are constituents separated in chromatography?
How are constituents separated in chromatography?
- Based on their differential retention on the stationary phase (correct)
- By their affinities for the solvent
- By altering the partition coefficient of the mixture
- Through interactions with the mobile phase
