Operation

OR 100/110 integrated dual-channel degasser

Principle of Operation

The OR 100/110 vacuum degasser has 2 vacuum chambers, degassing
tube, variable speed vacuum pump, microprocessor controller, sensor and
check valves. The solvent (mobile phase) flows through a degassing tube,
which is inside a vacuum chamber. In accordance with Henry’s Law, de-
creased pressure in the chamber causes the outward movement of gas
dissolved in the mobile phase across the tube wall, thus degassing the
mobile phase. The pressure in the vacuum chamber is established by the
vacuum pump and monitored by the microprocessor through an integrated,
absolute pressure sensor. Degassed mobile phase exits the vacuum de-
gasser and enters the pump.

Principles of degassing using Teflon AF

®

membranes

The fully amorphous nature of Teflon AF

®

has a molecular level porosity

superior to the mechanically induced porosity in extruded PTFE tubing in
many other devices. The very small surface area required to degas the
mobile phase, reduces the carryover from one solvent to another to virtu-
ally zero. Teflon AF

®

is inert to all solvents normally used in HPLC. How-

ever, Teflon AF

®

is soluble in perfluorinated solvents such as Fluorinert

®

FC-75 and FC-40 and Fomblin perfluoro polyether solvents. Use of such
