CLP Standards for ICP and ICP-MS
Contract Required Detection Limits - CLP ILM 02.0 Standards for ICP and CLP-M/6020/SW-846 Standards for ICP-MS

A standard must be run at two times the Contract Required Detection Limits (CRDL), or at least 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, Mg, and Na.

Our standard contains all of the required elements on the TAL, in their appropriate concentration ratios. CL-CRDL-1 should be diluted by a factor of 1,000 prior to use in the two times CL-CRDL run for ICP analysis. For analysis by atomic absorption, CL-CRDL-1 should be diluted by a factor of 2,000 prior to use in the one time CL-CRDL run.
