Question 1

What is the relationship between sample volume and detection limit?

  • Higher volumes allow detection of lower concentrations
  • Higher volumes increase detection limit
  • There is no relationship

💡 Hint: Consider how the volume you collect affects what you can potentially measure.

Question 2

True or False: The detection limit is the same as the sensitivity of an instrument.

  • True
  • False

💡 Hint: Think about the definitions of both terms.

Challenge Problems

Push your limits with challenges.

Question 1

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?

💡 Hint: Consider how you can calculate the volume based on your detection goal.

Question 2

In a scenario where the precision of your measurements varies significantly over time, how would you adjust your methodology to improve reliability?

💡 Hint: Think about how averaging can aid in minimizing random errors.
