2 Configuration
If other columns are currently defined, they may not use AUX 1,
Front inlet, Front detector, or Back detector in their
configuration.
Complicated example
The inlet feeds the analytical column which ends at a three- way
splitter. The splitter has the column effluent and makeup gas
coming in, and transfer lines (non- coated columns) to three
different detectors. This is a case where a sketch is necessary.
The oven was chosen for the MSD line since most of it is in the
oven.
As in the previous examples, your analytical method can control
the flow of column # 1 which has a GC pressure controlled inlet
and outlet.
