Show hintHide hint
Think about why we would need a similar compound.
Question 2.
How is the Minimum Detection Limit (MDL) calculated?
Show hintHide hint
Focus on the formula used for MDL.
3Question 3.
What is the purpose of a surrogate in analytical chemistry?
- To increase sample volume
- To estimate recovery of analytes
- To collect more data
Show hintHide hint
Think on the function of surrogates in estimation.
4Question 4.
True or False: The Maximum Detection Limit (MDL) is not important in sampling.
- True
- False
Show hintHide hint
Reflect on what MDL enables in analysis.
Question 5.
You have a sample with a concentration of 15 mg/L TSS and a standard deviation of measurements is 6 mg. Calculate the minimum volume required.
Show hintHide hint
Apply the MDL and the surface area of concentrations.
Question 6.
How does the choice of surrogate affect recovery rates in samples collected from industrial waste compared to natural waters?
Show hintHide hint
Consider the reasons behind selection based on chemical properties.
