Evaluation of the SFC-FID for the Olefin Analysis ASTM D6550 Method

SFC has been well established for gasoline and diesel fuel analysis, using the ASTM D5186 and D6550 methods. Both ASTM methods require a silica column for the separation, while D6550 requires the use of an additional silver column for retention of the olefins. In this application note, the ability of SFC-FID to meet the specifications of the ASTM D6550 method was evaluated.
