Evaluation of the SFC-FID for the Olefin Analysis ASTM D6550 Method
Evaluation of the SFC-FID for the Olefin Analysis ASTM D6550 Method
10 Dec 2015SFC 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.

Supercritical fluid chromatography and extraction systems (SFC/SFE)
JASCO (USA)Over the years, JASCO has responded to the growing emphasis on reducing chemical waste by offering an alternative to traditional HPLC with a full line of “green” SFC/SFE products.The reduction in the use of organic solvents has cost, health and safety benefits as well as faster, cleaner sample recovery during experimental procedures. The benefits of using supercritical fluids are their liquid-like densities offering higher solubility and increased column loading. They have low viscosity and are highly diffuse enabling faster separation and extraction.
