Question 1.
What is a surrogate in analytical chemistry?
Show hintHide hint
Think about why we use a similar substance.
Question 2.
What is recovery efficiency?
Show hintHide hint
Consider the definition of efficiency.
3Question 3.
What is the primary purpose of a surrogate in recovery analysis?
- To enhance the analyte
- To mimic the analyte's behavior
- To replace the analyte entirely
Show hintHide hint
It is related to similarity in behavior.
