Custom Standards Request
CPI International Peak Performance™ Standards are prepared from high-grade starting materials, sub-boiling distilled acids, and 18-mega-ohm de-ionized water. We use only Class A volumetric labware and balances calibrated with Class F NIST-traceable weights. 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. Every standard is certified gravimetrically and instrumentally against NIST SRM 3100 series spectrometric solutions.
We also offer custom standards to reduce workload and increase 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% for 18 months from the date of shipment.
