GC-2010 Plus
3.5AFC and APC Control Ranges
For the AFC, the column inlet pressure can be set from 0 to 970 kPa, and the total flow rate
can be set to 0 to 1,200 ml. (Refer to Figs. 3.5.1 and 3.5.2.) However, these values are
instrument specifications, valid when the primary pressure supplied to the GC-2010 Plus is
980 kPa.
The allowable pressure and flow rate settings are limited by the primary pressure, as shown
in Fig.3.5.1, Fig.3.5.2. In addition, the pressure settings are limited by the column type and
the purge flow rate.
NOTE When options are added to the flow line, the range above becomes narrow.
