Used for preparing and storing samples. 3.1.3 Test sample; A test port is a sample obtained by further homogenization of all or part of a laboratory sample for analysis or testing. 3.1.4 The change in sensitivity results divided by the corresponding concentration standard curve; That is to analyze the slope of the calibration curve. The detection limit of qualitative methods refers to the minimum concentration or content at which the detected substance can be reliably detected. However, quantification is not necessary and has been proven through collaborative experiments or confirmed by a single laboratory
Function of testing report:
