Challenge Problems

Push your limits with challenges.

Question 1

During your gas chromatography analysis, you find that the calibration curve has a slope of 0.1 and an intercept of 200. Discuss what this indicates about your calibration and how you might improve its reliability.

💡 Hint: Reflect on the importance of the slope value in calibration.

Question 2

You are tasked with finding the concentration of a biologically active compound in a sample that could exhibit systematic loss during analysis. Outline a systematic approach for calibrating this compound to ensure accuracy.

💡 Hint: Consider why consistency throughout calibration is key.
