Preparing the GC

Installation Guide: TCD-to-FID Series Connection
1 Turn off the detectors.
2 Set the oven to 25 °C and turn off all other heated zones.
3 Turn off all carrier and detector gases at their sources.
Carrier gas flow must be maintained until the column has cooled to avoid
column damage.
4 Turn off the main power switch.
5 Disconnect the power cord from the power source. Some
internal parts carry power if the cord is connected.
6 Remove the column(s) and any associated hardware from
inside the column oven.
7 Lift the hinged GC top cover at its front edge to expose the
detector area. Remove the cover by raising it to vertical,
lifting its left hinge pin from its bracket, and then sliding the
cover to the left to free its right hinge pin.
Perform this procedure only if necessary to add a new detector,
or to remove and replace an existing detector. Remove the
panels indicated in the following steps. Note that if an existing
detector is being completely replaced by a new detector,
carefully store the old detector assembly and all associated
parts in a safe place for possible future use.
1 Remove two screws along the lower edge of the left side (flow
control) panel. Slide the panel slightly to the rear and lift it
off.
Electronic components can be damaged by static electricity: use a
properly grounded static control wrist strap when removing the
electronics panel.
