What is the critical threshold in measurements?
Question 5.
A water sample yields a TSS reading of 0.3 mg/L, but the detection limit of your instrument is 0.5 mg/L. Discuss the implications of this discrepancy.
Show hintHide hint
Think about what it means to measure below detection limits.
Question 6.
You take repeated measurements of the same water sample and receive varied results due to fluctuations. Propose a methodology to enhance measurement reliability.
