Challenge Problems

Push your limits with challenges.

Question 1

A chemist performed a series of dilutions on a sample, but still received inconsistent peak responses in chromatographic analysis. What steps can they take to improve the situation?

💡 Hint: Think about what might cause variability in detection and how to standardize it.

Question 2

With a newly developed method of chromatography, it has been reported that sensitivity is low for certain compounds. What factors could be contributing to this issue and how would you evaluate potential solutions?

💡 Hint: Consider the different stages of the chromatography process where problems can arise.
