Challenge Problems
Push your limits with advanced challenges
A study shows that a surrogate added to a sample yields a recovery rate of 85%. If the initial concentration of the surrogate was 150 mg/L, calculate the amount quantified during analysis.
💡 Hint: Use the recovery percentage to find the actual quantified amount.
Discuss a scenario where matrix interference significantly impacted an environmental study's results, and provide potential solutions to mitigate this issue.
💡 Hint: Think about specific pollutants and potential interfering compounds.
