LC-23C COLUMN HEATING
COMPARTMENT
The LC-23C is specifically designed to fit within the BAS CC-5 Column Compartment. The
CC-5 is pre-drilled to accept a Rheodyne injection valve on the front panel. It has several
grooves on both sides for convenient access to external detectors.
If you are installing the LC-23C as an upgrade to a BAS electrochemical detector or BAS
480 Liquid Chromatograph, and already have a cell preheater installed in the CC-5, you
may wish to remove it. Routing the tubing from the LC-23C to the cell preheater and then
to the detector is difficult due to space limitations. The LC-23C alone will provide
satisfactory temperature control for the electrochemical cell if you keep the cover closed
during operation.
Before installing the LC-23C, give some thought to the configurations of the column(s) you
intend to use. Some configuration using compact BAS cartridge columns are diagrammed
in Figure 5. You can also leave the analytical column outside the LC-23C (at room
temperature) and heat a post-column reactor (tubing coil, packed bed) within the LC-23C.
