Alfa Aesar Ion Chromatography Standards save you money by eliminating the need to prepare and qualify your own IC standards. We've already done the work for you. Each of our standards is NIST traceable, so you can feel confident with your results when using them.
Specpure® is Alfa Aesar's trademark for a comprehensive range of standards. Our IC standards are made using Puratronic® starting materials (typically 99.999% pure) and 18 megaohm deionized water. All standards are pre-filtered to minimize column plugging and maximize shelf life. All Alfa Aesar standards are accompanied by a Certificate of Analysis which states the actual concentration and the traceability to NIST. Most are guaranteed to be stable for one year from the ship date, provided they are kept tightly capped and stored under normal laboratory conditions. Alfa Aesar's stringent quality guidelines, vast experience, and exceptional production control result in a standard you can trust.
