Analysis by Fluorescent Indicator in Liquid Chromatography

This analysis, abbreviated as FIA for Fluorescent Indicator Adsorption, is standardized as ASTM D 1319 and AFNOR M 07-024. It is limited to fractions whose final boiling points are lower than 315°C, i.e., applicable to gasolines and kerosenes. We mention it here because it is still the generally accepted method for the determination of olefins. [Pg.79]

Chapter 3. CHARACTERIZATION OF CrUDB OiLS AND PETROLEUM FRACTIONS [Pg.81]

As stated earlier, these hydrocarbons are difficult to quantify with accuracy. The FIA method, which is a chromatographic adsorption on silica, gives volume percentages of saturated hydrocarbons, olefins and aromatics. [Pg.81]

Some attempts, not yet very convincing, have been made to extend the field of application to gas oils by heating the column. [Pg.81]
