Standard Test Method for Determination of Fluoride and Glycol Degradation Products in Engine Coolants by Ion Chromatography

Importancia y uso:

5.1 This test method is for the quantitative determination of fluoride and glycol degradation products in engine coolants. By this method, analysis can be performed directly without pretreatment, other than dilution, as required by the linear ranges of the equipment. Table 1 indicates applicable analytes and approximate detection limits.

(A) Sample diluted ¹/₁₀ with reagent water, suppressed conductivity detection, IonPac AS20 column with AG20 guard column. Other systems will require MQL determinations using chosen dilution factors, eluents, columns, and detector.
