Inorganic Standards

CPI International Peak Performance™ ICP, ICP-MS, and AA Standards are prepared from high-purity starting materials, sub-boiling distilled acids, and 18-mega-ohm de-ionized water. Class A volumetric labware and balances calibrated with Class F NIST-traceable weights are used. All of our solutions are bottled in either HDPE or LDPE bottles that have been pre-cleaned, pre-leached and secured with heat-shrink seals. Standards are certified gravimetrically and instrumentally against NIST SRM 3100 series spectrometric solutions and are compliant to ISO 17025 and ISO 17034.

Custom standards are also available to reduce workload and increase efficiency in laboratories.

A Certificate of Analysis is supplied with every standard and the accuracy of single element standards is guaranteed to ±0.3% with at least 12 months of expiration from date of shipment. Safety data sheets are available at sds.cpiinternational.com.
