Instrument Check Standards

CPI International distributes an advance line of Instrument Checking Standards designed for evaluating the calibration curves as Initial Calibration Verification (ICV) and Continuing Calibration Verification (CCV) solutions. Our multi-element Peak Performance™ standards are traceable to NIST reference materials and formulated for fast and precise laboratory analysis.

We also offer custom standard solutions to reduce workload and increase operational efficiency in laboratories. Our reference materials are available in 1mL ampules or two 0.6mL ampules to increase your shelf life at no additional cost.

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.
