Challenge Problems
Push your limits with advanced challenges
You are analyzing surface water for pollutants, and a sample shows significant loss of analytes during transport. Propose at least three strategies to avoid such losses in the future.
💡 Hint: Think about protective measures you’d use for preserving food.
During an experiment with surrogate standards, the results indicate that the standards yielded a 50% recovery rate. If the original concentration was 200 mg/L, what will the adjusted concentration of the analyte be after recovery adjustment?
💡 Hint: Consider how to scale up the concentration based on the recovery percentage!
