Challenge Problems
Push your limits with advanced challenges
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.
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.
