2 cards from this section. Quick, good the night before a test.
What is a surrogate in environmental analysis?
Think about what role it plays in mimicry during analysis.
Why is concentration important in analytical chemistry?
Consider the relationship between concentration and detection.
What is the purpose of using a surrogate in analysis?
Think about how they relate to the analytes you're studying.
True or False: Calibration is not necessary if the recovery percentage is high.
Consider what calibration helps achieve regardless of recovery.
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?
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?
Think of how analysts can maintain consistency across experiments.
