New published: The advanced ASTM D8193
ASTM D8193 employs a direct IR transmission measurement of oils and greases in the extraction solvent. The method does not require any solvent evaporation like gravimetric or solventless IR methods and can therefore be used to measure all fractions of the sample, including the light ends. Furthermore, a more complete fraction of extracted hydrocarbons are accessible by this method as compared to GC methods that do not detect fractions eluting outside the defined time window.
Correlation to international standards
With its easy and intuitive operation, ERACHECK ECO enables the straightforward creation of user calibrations and correlations. Ensuring excellent correlation with other established oil-in-water methods like the gravimetric method EPA 1664A, IR-methods ASTM D7678, ASTM D7066 and ASTM D3921, as well as the gas chromatography “OSPAR” method ISA 9377-2.
