Consider how the volume you collect affects what you can potentially measure.
True or False: The detection limit is the same as the sensitivity of an instrument.
Think about the definitions of both terms.
You need to measure TSS in a lake with an expected concentration of 0.3 mg/L. Your balance's detection limit is 0.1 mg/L. What is the minimum sample volume you would need?
Consider how you can calculate the volume based on your detection goal.
In a scenario where the precision of your measurements varies significantly over time, how would you adjust your methodology to improve reliability?
Think about how averaging can aid in minimizing random errors.
