This standard is produced for refineries performing Detailed Hydrocarbon Analysis (DHA) of crude oil feedstocks and fuels. It helps with calibrating complex hydrocarbon analyses and provides the greatest number of gravimetrically determined values for qualitative calibration to help our customers optimize production and maximize profitability—while fulfilling requirements such as ASTM Methods D6729, D6730, and D6733.
