Question 1.
What is volatilization?
Show hintHide hint
Think about how liquids can change states!
Question 2.
Name one way to reduce adsorption losses.
Show hintHide hint
Consider the materials used in sample collection!
3Question 3.
What is one major effect of volatilization on analyte concentration?
- It increases the concentration of the analyte.
- It decreases the concentration of the analyte.
- It has no effect on concentration.
Show hintHide hint
Think about what happens to a puddle of water on a hot day.
4Question 4.
True or False: Adsorption can lead to an increase in analyte concentration.
- True
- False
Show hintHide hint
Remember how surfaces can attract particles!
Question 5.
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.
Show hintHide hint
Think about protective measures you’d use for preserving food.
Question 6.
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?
Show hintHide hint
Consider how to scale up the concentration based on the recovery percentage!
