For a carrier gas, its tube is connected at the fitting on the
appropriate mass flow controller labeled IN.
C
For a capillary makeup gas, its tube is connected at the fitting on
the appropriate flow manifold block labeled FID—AUX for an FID or
NPD, or TCD—AUX for a TCD or ECD.

and air for an FID or NPD , their tubes are connected at
fittings on the appropriate flow manifold block labeled, respectively,
FID—HYD and FID—AIR.
C
For TCD reference gas, its tube is connected at the fitting on the
appropriate flow manifold block labeled TCD—REF.
Once all connections are made, proceed to Setting initial supply
