which is then determined radiometrically to give a measure of the original chloride
concentration. The detection limit can reach 0.05ppm chloride.

2.17.13 Ion chromatography
Various workers have discussed the codetermination of chloride with other anions [201-
203]. This is discussed further under multianion analysis in sections 12.2.1, 12.2.4, 12.2.5
and 12.2.6.

2.17.14 High performance liquid chromatography
Stetzenbach and Thompson [138] employed high performance liquid chromatography on
anion exchange columns to determine chloride in admixture with bromide, iodide, nitrate
and thiocyanate in non saline waters. This method is discussed further under multianion
analysis.
Moss and Stephen [139] have described the determination of chloride (and bromide,
iodide and phosphate) in non saline waters by high performance liquid chromatography.
Salov et al. [115] determined chloride (and bromide, iodide, iodate, bromate and
chlorate) by high performance liquid chromatography using inductively coupled argon
plasma mass spectrometry as a detector.
The application of this technique is also discussed under multianion analysis in
sections 13.1.1.1, 13.1.1.2, 13.1.1.5 and 13.1.1.7.

2.17.15 Ion exclusion chromatography
The application of this technique is discussed under multianion analysis in section
