FIA Hydrocarbon Types

Superior separation of your petroleum fractions
ASTM D1319, IP 156, IP 3837,

								ASTM D1319,

Designed for precision, adjustable to perfection

Ensuring full compliance with ASTM D1319, IP 156, and IP 3837, Ayalytical Instruments’ FIA (fluorescence indicator adsorption) apparatus is ideal for the determination of hydrocarbon types over the concentration ranges of 5-99 volume percent aromatics, 0.3-55 volume percent ole fins, and 1-99 volume percent saturates, in petroleum fractions that distill below 315ºC (599ºF). The FIA extraction procedure is performed by placing a 0.75 mL sample of liquid petroleum into a glass column packed with activated silica gel and a thin layer of fluorescent dyed gel. After the petroleum sample has been adsorbed onto the surface of the gel, alcohol is added to adsorb the sample to separate the hydrocarbons. The fluorescent dyes are then selectively separated into aromatic, ole fin, and saturate zones, which are visible under ultraviolet light. Finally, each separated zone is calculated by volume percentage.

The FIA apparatus is available in three models, and is comprised primarily of a wall mounting panel with universal brackets and mounting fixtures for the secure retention of 2, 4, or 6 glass testing columns. For each position, the instrument is equipped with one easy-to- read pressure gauge, one pressure manifold with precision needle valve, one spherical joint/hose connector, and one complete standard adsorption column. Additional implements included with this apparatus include a zone measuring device for accurate volume percent determination and portable UV lamp for optimal zone visibility.

Note: Ayalytical Instruments’ FIA extraction apparatus does not include a fixed mounted vibrator. Rather, we recommend a handheld vibration unit (sold separately), which allows for increased operator control in concentrating vibration when packing silica gel into the test columns.
