Frequently Asked Question
Questions asked by users might not always be phrased in the clearest way.
Analytical sensitivity is defined as: a) The intensity of the signal b) Standard deviation of measurements c) The intercept in the standard curve d) The noise level in a blank measurement e) The slope of the concentration-response curve divided by the standard deviation of the measurement
Accepted Answer
Analytical sensitivity is the smallest concentration of analyte that can be reliably detected by a given analytical method. It is related to the slope of the calibration curve, which represents the change in signal per unit change in concentration, and the standard deviation of the blank (noise). Therefore, the correct answer is E).
