Question 1

What is the purpose of sensitivity in analytical methods?

  • To determine the weight of a sample
  • To detect small amounts of changes in analyte concentration
  • To measure temperature

💡 Hint: Think about what sensitivity helps with in detecting chemicals.

Question 2

True or False: The Minimum Detection Limit indicates the highest concentration an instrument can measure.

  • True
  • False

💡 Hint: Remember what MDL stands for.

Challenge Problems

Push your limits with challenges.

Question 1

Given a sample with a concentration of 0.75 mg/L and an instrument that cannot detect below 1 mg/L, outline the steps to prepare the sample for detection.

💡 Hint: Consider ways to increase concentration without losing the analyte.

Question 2

Assuming a calibration curve shows a linear relationship with a slope of 2 and a y-intercept of 0.5, derive the concentration of an analyte that gives an instrument response of 4.

💡 Hint: How do you use the slope and intercept to calculate concentration?
