作为独立的CLP QA标液，配合校准标液使用，在每一选择样品分析用波长下，验证工作曲线。通常稀释至工作曲线浓度范围内。对于ICV-2A, PLSB7-2X, ICV-2C，推荐稀释200倍，对于ICV-1A, ICV-3，推荐稀释20倍。
The US EPA retains analytical services through the Contract Lab Program (CLP). The CLP follows detailed SOPs derived from EPA methods. The CLP methods require calibration of analytical instrumentation within the expected quantitative range (ICAL standards) and additional CLP QA standards (ICV standards) to verify the calibration curve at each of the selected wavelengths that will be used for sample analysis.
Our verification standards, ICV-1A, ICV-2 an ICV-3, contain all of the elements on the TAL list and are independent standards for testing an instruments calibration curve. SPEX CertiPrep’s ICV standards are designed to be used with their corresponding instrument calibration standards (ICAL). We recommend dilution of ICV standards to a range within your instruments calibration curve. A dilution of 200-fold is recommended for ICV-2A, PLSB7-2X and ICV-2C. A dilution of 20-fold is recommended for ICV-1A and ICV-3.
