ICP Multi-Component Stock Solution Standard with 26 Components in 2% HNO₃+Tr HF.

Used in preparing working calibration standards and instrument performance check standards. These working calibration solutions are prepared from the stock solutions by making 100-, 20- and 10- fold dilutions. The working matrix is 1% HNO₃. To prepare an instrument check standard, the stock solution is diluted 40 fold in 1% HNO₃.

This standard is traceable to NIST SRM 3100 series. ISO 9001:2015 certified, ISO/IEC 17025:2017 and ISO 17034:2016 accredited.

12 month expiration date.
