ICP-MSClaritas PPT Grade CRMs are designed for ICP and ICP-MS analysis. They are available in single and multi-element solutions. The standards are at 1 ug/mL, 10 ug/mL, 100 ug/mL, or 1,000 ug/mL and packaged in 30 mL and 125 mL bottles to minimize contamination. They are made using high purity acids, the highest grade starting materials and high purity water in order to minimize contaminants. Custom standards can be manufactured upon request.
