About the Purged Packed Column Inlet
This inlet is used with packed columns when high-efficiency separations are not required. It
can also be used with wide-bore capillary columns, if flows greater than 10 mL/min are
acceptable.
If the columns are not defined (packed columns and undefined capillary columns), the inlet is
usually flow-controlled. If capillary columns are used and the columns in the flow path are
defined, the inlet is normally pressure-controlled but can be put into the flow control mode.
