Custom Inorganic Standards Request

Reduce workload and increase efficiency in laboratories with CPI International’s Custom Inorganic Standards! Our CRMs are prepared from high-grade starting materials, sub-boiling distilled acids, and 18-mega-ohm de-ionized water. All of our inorganic custom reference materials are bottled in either HDPE or LDPE bottles that have been pre-cleaned, pre-leached and secured with heat-shrink seals. Every inorganic standard is certified gravimetrically and instrumentally against NIST SRM 3100 series spectrometric solutions.

CPI’s custom inorganic reference materials are available in 100mL, 250mL, 500mL, and 1L volumes. An ISO 17034 compliant Certificate of Analysis is shipped with every standard. Most custom standards have a shelf life of 18 months from the date of shipment.
