1.1 This test method is valid for the simultaneous determination of the inorganic alkali and alkaline earth cations, lithium, sodium, potassium, magnesium, and calcium, as well as the ammonium cation in reagent water, drinking water, and wastewaters by suppressed and nonsuppressed ion chromatography.
1.2 The anticipated range of the method is 0.05-200 mg/L. The specific concentration ranges tested for this method for each cation were as follows (measured in mg/L):
| Lithium | 0.4-10.0 |
| Sodium | 4.0-40.0 |
| Ammonium | 0.4-10.0 |
| Potassium | 1.2-20.0 |
| Magnesium | 2.4-20.0 |
| Calcium | 4.0-40.0 |
1.2.1 The upper limits may be extended by appropriate dilution or by the use of a smaller injection volume. In some cases, using a larger injection loop may extend the lower limits.
1.3 It is the user's responsibility to ensure the validity of these test methods for waters of untested matrices.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For hazards statements specific to this test method, see 8.3.
