SOLVED: Detection limit. In spectrophotometry, we measure the concentration of analyte by its absorbance of light. A low concentration sample was prepared, and nine replicate measurements gave absorbances of 0.0047, 0.0054, 0.0062, 0.0060, 0.0046, 0.0056, 0.0052, 0.0044, and 0.0058 in a 1.000-cm cell. Nine reagent blanks gave values of 0.0006, 0.0012, 0.0022, 0.0005, 0.0016, 0.0008, 0.0017, 0.0010, and 0.0011.(a) Find the absorbance detection limit with Equation 5-2.(b) The calibration curve is

SOLVED:Consider a sample that contains analyte at the detection limit defined in Figure 5-2. Explain the following statements: There is approximately a 1 % chance of falsely concluding that a sample containing no analyte contains analyte above the detection limit. There is a 50 % chance of concluding that a sample that really contains analyte at the detection limit does not contain analyte above the detection limit.

New episode of #BenchBoost! 🎙 In this episode, our team discusses detection limits. They cover the differences between instrument detection limits and method detection limits, detailing how each is calculated and the importance of optimizing conditions to achieve the lowest possible detection limits. The discussion includes practical tips for enhancing detection limits through sensitivity adjustments, stable measurements, and proper sample preparation. The need for periodic reevaluation of dete
