USEPA Method 9058 DETERMINATION OF PERCHLORATE USING ION CHROMATOGRAPHY
1.0 SCOPE AND APPLICATION
1.1 This method describes the determination of the perchlorate anion in water by ion
chromatography.
1.2 The applicable matrices are listed below.
1.2.1 This method has been found to perform adequately on water samples with
conductivities up to 1000 μS/cm. Water samples with conductivities >1000 μS/cm have not
been tested.
1.2.2 This method is potentially applicable to surface water, mixed domestic water,
and industrial wastewaters.
1.3 A method detection limit (MDL) for perchlorate in reagent water has been calculated
to be 0.7 μg/L (pooled data, see Table 1). The MDL for a specific matrix will differ from that listed,
depending upon the nature of the sample. When MDLs are needed for a specific project, matrixspecific
MDL studies may provide data users a more reliable estimate of method detection
capabilities.
