3 cards from this section. Quick, good the night before a test.
What is chromatography used for?
Think about how different compounds behave in mixtures.
Name the two phases involved in chromatography.
Consider what stays still and what moves.
What is the main purpose of chromatography?
Think about what happens during the chromatography process.
The stationary phase in chromatography is moving. True or False?
Consider the definitions of stationary and mobile.
You have a water sample containing three unknown pollutants, A, B, and C. Pollutant A has a K of 10, B has a K of 5, and C has a K of 1. If you need to isolate pollutant C efficiently in a chromatography setup, what considerations must you take into account?
Think about how different K values impact the time each pollutant interacts with the stationary phase.
If decreasing the mobile phase flow rate leads to better resolution in chromatography, how would implementing a slower flow impact the overall time taken for an analysis?
Consider the balance between efficiency and time.
