This standard specifies the general laboratory requirements for pesticide residue analysis, as well as the analysis of analysts, basic resources, and analytical processes.
Claim.
This standard applies to the management and guiding operation of a good laboratory for pesticide residue analysis.
2 Terms and definitions
The following terms and definitions apply to this document.
2.1
Accept limit acceptedlimit; AL
The amount of analyte that meets regulatory limits or guidelines. Such as MRL, MPL; commercial standards, target concentration limits (meal storms)
Exposure assessment), acceptable level (environment), etc., for substances without MRL or for substances that are banned, there may be no AL value (actually
Residues with zero or no limits), or exceeding the target concentration, should be corroborated (execution limits or regulatory limits).
2.2
Accuracy
The degree to which the test results are consistent with acceptable reference values.
2.3
Alpha error alpha(α) error
The actual concentration of the analyte in the sample is below a certain value (such as AL), but in multiple tests, the measured value of individual tests is higher than this specific
The value (false positive), the probability of this happening is called alpha error, the probability of a false positive result. Usually this probability is acceptable
Between 1% and 5%.
2.4
Analyte
A chemical substance that is inspected or measured in a sample.
2.5
Analyte uniformity (in sample) analytehomogeneity(insample)
The consistency of the analyte in the matrix. The difference in analysis results caused by the sample processing process is closely related to the size of the sampled portion.
The relationship between the sampling constant and the size of the sampled portion and the expected variation is.
Ks=w(CVSp), where w is the mass of the analysis part and CVSp is the score of the w(g) analysis sample extracted from the analysis part
The coefficient of variation of the analyte content.
2.6
Analysis section of actualportion
A representative, appropriate amount of the fraction for residual content measurement taken from the analytical sample.
2.7
Analytical sample analyticalsample
Analytical samples with minimal sampling error prepared from laboratory samples by separation, mixing, comminution, fine pulverization, etc.
