EPA Method 300.0:
Inorganic Anions by Ion Chromatography. Official Name: Determination of Inorganic Anions by Ion Chromatography

A small volume of sample, typically 50-100 uL, is introduced into an ion chromatograph. The anions of interest are separated and measured, using a system comprised of a guard column, separator column, suppressor device, and conductivity detector.

Part A of the test method covers the determination of common inorganic anions in drinking water, surface water, mixed domestic and industrial wastewaters, groundwater, reagent waters, solids (after extraction), leachates (when no acetic acid is used). Part B of the test method covers the determination of bromate, chlorate, and chlorite in drinking and reagent waters.

Methods for the Determination of Inorganic Substances in Environmental Samples (EPA/600/R-93/100)

(1) Coeluting species (e.g., low-molecular-weight organic acids). (2) High concentration of anions can effect resolution of peaks and elution times. (3) Fluoride is especially sensitive to coeluting species, and "water dip" (corresponding to the elution of water) at low concentrations.

QC Requirements:
Calibration Blank (CB), Quality Control Sample (QCS), Performance Evaluation Sample (PE), Instrument Performance Check Solution (IPC), Laboratory Duplicate (LD), Field Duplicate (FD), Laboratory Fortified Matrix (LFM), Laboratory Fortified Blank (LFB), Laboratory Reagent Blank (LRB), Linear Calibration Range (LCR)

Maximum Holding Time:
Part A: 48 Hours (NO2-N, NO3-N, orthophosphate-P) 28 days (others)Part B: Bromate and Chlorate (28 days) and chlorite (14 days with preservation -- otherwise analyze immediately).



DL - * (* Upper detection limit is defined as the highest calibration point, as determined by analyst.)

Precision and accuracy were obtained from a single operator study, analyzing 7 replicate reagent water samples. Additional precision and accuracy data, including data from different matrices, are available in the method.
