The IonPac® Cryptand C1 Concentrator Column is recommended for the analysis of trace perchlorate in drinking water. This adjustable-capacity column contains a macroporous, 17.5 μm resin grafted with the macrocyclic 2,2,2 cryptand compound. The column’s functional capacity depends on eluent concentration and the type of cation bound within the cryptand molecule.
Approximay 30 μeq/col of cryptand capacity available for use
Capacity adjustable from fixed amount to zero by via eluent concentration or cation type
The adjustable capacity makes the Cryptand C1 a powerful tool for determining trace perchlorate in drinking water and high ionic strength water. Methods using the C1 can quantify 140 ng/L of perchlorate in a background of total dissolved solids with concentrations as high as 3000 mg/L. The Cryptand C1 is specified for sample preconcentration in US EPA Method 314.1.
