Assurance is SPEX CertiPrep’s answer to the necessity for accuracy, purity and high quality in a plasma emission standard. With many laboratories utilizing ICP-AES spectroscopy for its speed and performance, and upgrading from atomic absorption techniques, we have enhanced our product specifications to meet these growing needs.

• ICP Standards, ICP-MS Standards, and AA Calibration Standards
• Speciation Standards
• Incomparable Certification
• Choice of 70 Elements
• 1,000 and 10,000µg/mL Concentrations
• 100mL, 250mL and 500mL Quantities
• Choice of Matrix for Most Elements (ex: Hydrochloric Acid, Nitric Acid, Water)

Assurance standards, single-element standards designed specifically for Atomic Absorption Spectroscopy, Graphite Furnace Atomic Absorption Spectroscopy, Optical Emission Spectroscopy, and ICP-AES analyses, are available from SPEX CertiPrep. The Assurance product line offers the quality in a calibration standard, for both AA and ICP-AES instrumentation, which today’s methods require. With each solution you will receive a Certificate of Analysis that lists the actual measured value of the main element, by two independent methods and reports actual measured impurities of up to 30 elements which may be present in the final solution. Each Assurance standard is manufactured under an Underwriter’s Laboratories, Inc. internationally accredited ISO 9001 quality assurance program. As always SPEX CertiPrep Triple Checks for Quality each standard produced.

SPEX CertiPrep analyzes each standard in our state-of-the-art laboratory, where the solutions are compared to United States National Institute of Standards and Technology solutions (where available). We guarantee the concentration of the major element to ±0.5%, and the accuracy and stability of each Assurance standard for one year from the date of shipment. All results are reported directly on the corresponding Certificate of Analysis.

SPEX CertiPrep uses only high purity acids, ASTM Type I filtered high purity water, and inorganic compounds or pure metals with a 99.99% to 99.9999% range of purity to help guarantee the best product available. The high purity starting materials and SPEX CertiPrep’s comprehensive Certificate of Analysis, reporting what is actually in your solution, are your assurance that emissions detected are real and are not due to unreported impurities in the calibration standard.
