FIA analysis of hydrocarbon types in petroleum products

Conforms to ASTM D 1319

Multiple samples: A single or up to six (6) multiple samples may be analyzed simultaneously since each station of the system may be operated independently.
Ball O-ring connections: The connection for each Upper Column is an O-Ring type ball joint which will seal without grease under moderate clamping pressure of the Stainless Steel Clamps provided with the system.
Convenient column connectors: Awkward vinyl tubing sleeves have been replaced with convenient O-Ring compression type fittings to connect the lower 3mm x 1200mm analyzer tubes to the Upper Columns. Internal geometry of the fittings is optimized for transition between tubing diameters, and a simple twist of the nut releases the Analyzer Tube.
Column support tip: The same type of connection is used to cap the lower end of each Analyzer Tube. An internal porous polyethylene support disc inside the fitting is positioned at the very bottom of the 3mm tube to support the silica gel packing. Like the fittings above, these Support Tips are attached or removed with a simple twist of the nut, and are used over and over again.
Individual pressure regulator valves: Each station has its own independent pressure regulation valve which may be set at any point from 0-15 psi, and will maintain the set pressure independent of changes in back pressure. An integral Pressure Gauge on each station continuously registers active pressure on each column.
Integral vibration: Electric vibration unit(s) are mounted to the upper chassis so that all column may be vibrated during the dry gel packing procedure, The 4-Station System has one vibrator, while the 6-Station System has two. Vibrators feature individual On/Off switch and amplitude selector switch.
Accessories included: With each system is included a 1ml syringe with 4" long needle for sample application, two plastic gel bottles for convenient pouring of silica gel during dry packing, extra O-Rings, stainless steel ball and socket joint clamps, two mounting brackets with screws for stabilizing chassis, and Operating Instructions.
