Challenge Problems
Push your limits with advanced challenges
If you start with a 50 ml water sample and perform an extraction that recovers 20 micrograms of an analyte added at 100 micrograms, what steps would you take to improve your recovery rate?
💡 Hint: Review methods to enhance extraction efficiency.
In a study, researchers performed multiple extractions but observed recovery rates varying from 30% to 70%. What could contribute to this variability and how might they standardize their protocols for consistent results?
💡 Hint: Think of how analysts can maintain consistency across experiments.
