Question 23 Which of the following is INCORRECT? O Calibration determines the relationship between the analytical response and the concentration of analyte. O The range in the calibration curve between the relationship of analytical response and concentration of analyte is the concentration interval over which linearity, accuracy, and precision are all acceptable. O The detection limit (DL) or also known as the limit of detection (LOD) is the smallest concentration that can be reported with a certain level of confidence. O In external standard method, the signal (SA) is inversely proportional to the concentration of analyte (CA). Therefore, the formula is SA=KACA where the k is method's sensitivity.
