Challenge Problems
Push your limits with advanced challenges
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?
💡 Hint: 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?
💡 Hint: Consider the balance between efficiency and time.
