In analytical chemistry, the detection limit, lower limit of detection, or LOD (limit of detection), often mistakenly confused with the analytical sensitivity, is the lowest quantity of a substance that can be distinguished from the absence of that substance (a blank value) with a stated confidence level (generally 99%). The detection limit is estimated from the mean of the blank, the standard deviation of the blank, the slope (analytical sensitivity) of the calibration plot and a defin… WebbSCIENCE IN CHEMISTRY SCH 7110: ADVANCED ANALYTICAL CHEMISTRY DATE: MAY 2024 TIME: 2 HOURS INSTRUCTIONS: Answer Questions one and any other two.
