For ILM 05.3，一个标液必须在合约检出限上运行。为验证合约检出限附近的线性情况，每次分析开始后，在使用验证工作曲线标液ICV/ICB之后，在干扰测试标液ICSA / ICSAB之前，使用此标液。
For ISM 01.2，至少一种校准标液浓度须在合约检出限附近，此标液稀释后作为校准标液，可做此用途。
For ILM 05.3, a standard must be run at the Contract Required Detection Limits (CRDL). To verify linearity near the CRQL, this standard is analyzed at the beginning of the analysis run, after the ICV/ICB and before the ICSA and ICSAB. In addition, this standard must be run at a frequency of not less than 20 analytical samples and at the end of the analysis run, followed by the ICSA/ISCAB. The sequence order is CCV, CCB, CRI, ICSA, ICSAB, CCV, and CCB.
For ISM 01.2, at least one of your calibration standards must be at the Contract Required Detection Limit (CRDL). This standard, when diluted, can be used as a calibration standard to fulfill this requirement.
