Alternatives for FIA to determine hydrocarbon type content
Apr 04 2019 Read 701 Times
PAC’s AC Analytical Controls offers multiple analysers for determining hydrocarbon type content. This is an important parameter for quality control of fuels. The analysis of these compounds is mandated in fuel standards to guarantee product usability, such as combustion properties, as well as compliance to environmental legislation.
To determine hydrocarbon type content, the Fluorescent Indicator Absorption (FIA) method according to ASTM D1319 is still widely in use in laboratories world-wide. Diesel specification ASTM D975, jet fuel specification DEF STAN 91-091 and ASTM D1655 refer to FIA as referee method for aromatic content. EPA legislation for reformulated gasolines lists FIA as the designated test method for olefin content and alternative method for aromatics content. Despite its wide usage, the FIA methodology is considered cumbersome and labour intensive. Various alternative test methods exist, which are easier to use and automate.
For gasoline, the AC Reformulyzer™ is the instrument of choice. This technology is standardised in ASTM D6839 and has proven to be a reliable and accurate tool for refiners since its introduction in the 1990’s. ASTM D6839 meets EPA requirements for use as an alternative method to D1319 for determine the volume percent of olefins in gasoline as per ASTM research report D-02-1818.
Another possibility for the analysis of hydrocarbon group types in middle distillates involves comprehensive 2-dimensional gas chromatography (GCxGC). Based on significant improvements to the flow modulator technology, AC Analytical Controls has developed the first dedicated analyser for routine group type analysis of (bio)diesel fuel products and jet fuels with a final boiling point up to 450°C. All solutions presented above can be ordered through AC Analytical Controls as guaranteed applications, delivered turn-key to your laboratory.
