合约检出限和仪器检出限高者，需运行标液于2倍检出限值进行检测。样品测试开始和结束前检测检出限，或者8小时班至少2次检测检出限。所有测试到的元素都需检测检出限，除了Al, Ba, Ca, Fe, Mg, Na, K元素。标液CRDL-1，对于ICP，在运行2倍检出限值检测前，应稀释1000倍使用；对于AA，在1倍值检测前，应稀释2000倍使用。
A standard must be run at two times the Contract Required Detection Limits (CRDL), or at two times the Instrument Detection Limits (IDL), whichever is greater. This standardization is performed at the start and the end of each sample analysis or at least twice in each eight hour shift. All elements to be analyzed must be run except Al, Ba, Ca, Fe, K, and Na.
Our CRDL-1 standard contains all of the required elements on the TAL, in their appropriate concentration ratios. CRDL-1 should be diluted by a factor of 1,000 prior to use in the “two times CRDL” run for ICP-AES analysis. For analysis by atomic absorption, CRDL-1 should be diluted by a factor of 2,000 prior to use in the “one time CRDL” run.
