Ethanol as a blending component for petrol - Determination of inorganic chloride and sulfate content - Ion chromatographic method; English version of DIN EN 15492:2009-01
This European Standard specifies an ion chromatographic (IC) method for the determination of the inorganic
chloride content in ethanol from 2,0 mg/I to 25,0 mg/I and of the sulfate content in ethanol from 0,9 mg/I to
15,0 mg/l.
NOTE Inorganic chloride content can be determined from 0,8 mg/I to 2,0 mg/I and sulfate content can be determined
from 0,4 mg/I to 0,9 mg/l. However, the precision was not established as no samples with chloride and sulfate contents in
these ranges where included in the interlaboratory test.
