Challenge Problems
Push your limits with advanced challenges
You have 5 liters of water containing an unknown analyte concentration. After performing SPE, you obtain a final volume of 10 mL and a measured concentration of 0.2 mg/mL in the extract. Calculate the concentration of the analyte in the original water.
💡 Hint: Think about how concentration relates to volume.
A liquid sample extraction results in a 75% recovery rate of an analyte. If the expected recovery was 40 micrograms, calculate how much of the analyte was actually recovered.
💡 Hint: Remember to multiply the expected recovery by the recovery percentage.
