Introduces the use of 6890 GC Split/Splitless Inlet electronic pneumatic control
This document describes the procedure for installing a split/splitless inlet with electronic pneumatic control (EPC) in an Agilent 6890 Gas Chromatograph. Before following this procedure, refer to the safety information on the inside front cover regarding hazardous voltages and proper disconnection of power sources.
The installation process involves preparing the GC by removing various covers such as the pneumatics top cover, RFI cover, inlet cover plate, side covers, fan cover, and tray mounting bracket. Subsequent steps include installing the insulation cover, attaching the flow manifold to the pneumatics carrier, and finally installing the inlet itself before restoring the instrument to operating condition.
The kit includes a split/splitless inlet with EPC, top and bottom insulation, a torx screw for the flow manifold, heat-resistant screws, an insulation cover assembly, small-hole and large-hole insulation pieces, and a static-control wrist strap.
You must unplug the power cord to avoid a potentially dangerous shock hazard caused by hazardous voltages present in the mainframe.
You need a T-20 Torx screwdriver to loosen the two screws that hold the inlet cover plate in place.
There are five captive screws that must be loosened to lift off the inlet cover.
