Ion Chromatography

Ion Chromatography (IC), a hybrid method, is a preferred method for the determination of inorganic and organic ions. Direct aqueous dissolution provides for assay detection limits of ppm to the percent range. For compounds that require conversion of organically bound elements, the detection limit is 0.05% or lower.

Proprietary techniques and the use of Dionex Instrumentation make it possible to analyze ion concentrations from ppb to the percent range without the chemical interferences that are normally associated with titrimetric and photometric assays.

Standard ions routinely analyzed at RML consist of SO4¯, Cl¯, Br¯, AcO¯, TFA ¯, I¯, PO4 ¯. Other ions are available but require a discussion with our chromatography specialist.
