4 II Specpure Specpure is the brand name for Alfa Aesar s comprehensive offering of spectrochemical analytical standard solutions. Specpure standards are unsurpassed in accuracy, purity and quality. Each product is guaranteed for one year from ship date and is shipped with a detailed certificate of analysis and an individual expiration sticker. We manufacture Specpure solution using the highest purity raw materials and ASTM Type I deionized water. Alfa Aesar s Atomic Absorption standards solutions are accurate to +/-1.0% and the Plasma solutions to +/-0.3%. Quality is assured by our adherence to strict QC standards, including: Balances routinely calibrated using NIST-traceable reference weights Class A volumetric labware is regularly calibrated All containers are inertness-tested, washed, preleached and triple rinsed in high purity water Solutions are verified both instrumentally against NIST-SRMs and by classical wet assay Alfa Aesar s single-element aqueous standards (both AA and plasma grades) are assayed using the High Performance ICP method (HP-ICP-AES) developed by NIST. This assures that these standards have the highest accuracy and the lowest uncertainty of any commercially available standards. Both the assayed concentration and the uncertainty are directly traceable to NIST-SRMs. Alfa Aesar s high purity starting materials, years of manufacturing experience and ISO Certified quality systems ensure a dependable analytical product.
