Interference Check Standards

CPI International showcases a premium collection of standards created for the purpose of enhanced and reliable interference checking. Our multi-element Peak Performance™ standards for this analytical application are designed for fewer calibratfion points and dilutions ideal in performing fast and accurate sample preparation and testing. 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.

A certificate of analysis and a material safety data sheet are shipped 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.
