DUS 2409: 2023, Standard test method for iron in trace quantities using the 1,10 phenanthroline method, Second Edition.; (15 page(s), in English)

This Draft Uganda Standard covers the chemical analysis of engine coolant for chloride ion by high-performance ion chromatography (HPIC). Several other common anions found in engine coolant can be determined in one chromatographic analysis by this test method. This test method is applicable to both new and used engine coolant. Coelution of other ions may cause interferences for any of the listed anions. In the case of unfamiliar formulations, identification verification should be performed by either or both fortification and dilution of the sample matrix with the anions of interest. Analysis can be performed directly by this test method without pretreatment, other than dilution, as required by the linear ranges of the equipment.
