AIN

The GC-Pro TCD allows separate gain adjustments on the TCD

amplifier. This affects the detector sensitivity and is most noticeable
when zeroing or making fine adjustments to the TCD detector as
described in Section 4.5.12.8. The amplifier gain can be set in the GAIN
field using a valve from 0-9 with 0 representing no gain and 9 the
maximum gain. Each component can have its own gain setting.

To set the gain, press the TIMING icon from the MAIN screen and

then press PARAMETERS. Select the component desired and then
EDIT. Enter a value from 0 to 9 in the GAIN field to set the desired gain
setting. Press ENTER and the save requester will appear which will
allow the gain setting to be changed (ENTER) or cancelled (CANCEL)
making no changes and returning the previous gain setting.

4.5.7 Temperature

Temperature control is a critical factor in GC analysis. The GC-Pro

TCD Analyzer incorporates three dedicated heaters with temperature
control PCBs.
