Challenge Problems

Push your limits with challenges.

Question 1

A spectroscopist notices a considerable baseline drift in their data. Describe the mathematical method they would use to correct this drift and how it impacts their subsequent analysis.

💡 Hint: Consider what mathematically represents the concept of a baseline.

Question 2

You have absorbance data from several standard samples, showing good linearity. Describe how you would assess the quality of the calibration curve fitted to this data.

💡 Hint: Remember how we judge linear relationships.
