(1) Define the need for the analysis (scope of analytes and matrices, concentration ranges, acceptable degree of accuracy, and tolerable rate of false negatives);
(1)确定分析所需（分析物和基质的范围、浓度范围、认可的精度、容许的假阴性率）；
(2) Define the primary analytical method(s) to meet the needs of the analysis most effectively and efficiently (e.g., GC-MS, LC-MS2, GC with selective detection, LC-fluorescence, and others);
(2)确定主要的分析方法以最高效地满足分析的要求（例如GC-MS、LC-MS2、定向GC、荧光LC，等等）；
(3) Conduct method validation of the primary method(s) for the targeted analyte(s) and matrix(es) (or representative analytes and matrices) to determine quantitative characteristics of the method(s) according to accepted practices;
(3) 参考惯例，针对目标分析物和基质（或者典型分析物和基质）的主要方法采取验证措施，确定定量分析特征的方法；
(4) At the same time as quantitative method validation, empirically determine MS criteria using samples of known concentrations on different days in fortified matrices to achieve the desired identification limit (with set criteria to minimize false negatives);
(4)同时作为确定的定性方法，使用强化基质中采用不同时间的已知浓度试样经验地确定MS标准，以达到期望的鉴定极限（通过设定标准以最小化假阴性）； |
