SPEX CertiPrep Claritas PPT standards are a class of certified inorganic reference standards designed specifically for today’s new generation of trace ICP-AES and ICP-Mass Spectroscopy instrumentation; and can also be used for traditional atomic spectroscopy methods. Based on extensive development, our chemists have formulated this line of high-purity standards for user convenience and stability, while providing documentation tailored to the low levels of detection.

The Claritas PPT selection of standards includes a complete series of single element solution standards, multi-element solution standards, many designed for use with US EPA Methods 6020 CLP-M, SW-846, and 200.8. These solutions are made with the highest purity materials available and are tested on our state-of-the-art ICP-MS under an internationally accredited ISO 9001 quality assurance program. For over forty years, our commitment to quality has made SPEX CertiPrep the leading manufacturer of inorganic reference standards.

Every Claritas PPT high purity standard is supplied with a comprehensive Certificate of Analysis which reports concentration of solution, as well as actual measured values in the final solution of both the major analytes and up to 68 trace element impurities at PPT levels. As always, each certificate includes NIST docu-mentation and information regarding the methods used. SPEX CertiPrep will guarantee the stability and accuracy of each Claritas PPT quality standard to ±0.5%, averaged labeled analyte concentrations, for one full year from date of shipment.

The Claritas line of single element standards includes Isotope Standards, a Gold Blank Standard, speciation standards, and matrix blanks.

The line of Multi-Element Solutions includes Tuning Solutions, Contract Required Quantitation Limit Standards (CRQL), Instrument Calibration and Instrument Check solutions, spike samples, calibration and matrix blanks.
