Methods and systems for the detection and quantification of multiplicity of ionic analytes comprising CrO, AsO, SeO, and ClO, and optionally F, Cl, NO, NO, SO, using ion chromatography and suppressed ion conductivity. The method comprises loading a sample loop with a sample; injecting the sample from the sample loop into a column with an eluent, wherein the column comprises a guard column and an analytical column; separating, with the column, the injected sample at an effective separation temperature the injected sample in the presence of an organic modifier into a multiplicity of detectable ionic analytes; suppressing, with a suppressor, background signal; and detecting, with a detector, the multiplicity of ionic analytes.
