Challenge Problems

Push your limits with challenges.

Question 1

You injected a standard solution of analyte A with a concentration of 100mg/L and received a detector response of 150 units. You also injected a sample with an unknown concentration and received a response of 75 units. Calculate the concentration of the unknown sample.

💡 Hint: Use the proportionality between measured response and concentration.

Question 2

Describe how you would design an experiment to determine the effect of temperature on the retention time of an analyte A. Include your control and variables.

💡 Hint: Consider what needs to stay the same for a fair test.
