As with SPEX CertiPrep’s Assurance and Plasma-Grade Standards, every Ion Chromatography (IC) Standard is prepared under our unique Triple Checked Quality Assurance Program. Only these standards are checked three ways with all results reported accurately on an informative Certificate of Analysis and are NIST traceable (where applicable). Cyanide Reference Standards are available in simple form : potassium cyanide (KCN), and a complex form (K₃ Fe (CN)₆). Also available are a variety of Ion Chromatography Instrument Check solutions, Matrix Blanks, and buffer solutions.

SPEX CertiPrep's unique Triple Checked for Quality® just got better. We now triple check our products for quality twice.

The Starting Material

• Stoichiometry of starting material
• Trace cation/anion standard impurities by ICP-AES or ICP-MS or IC
• CL, SO4, checked by classical wet chemistry

The Final Solution

• ICP-AES or IC for the major element
• Classical wet assay for major element
• Final ICP-AES or ICP-MS or IC analysis for trace cation/anion impurities on the actual solution
