    Lc-23a column heating compartment 1. Place the lc-23a heating compartment in the desired location. Six holes with captive 6-32 threads are provided for secure mounting on your liquid chromatograph, if desired. The holes are positioned to fit early model (pre 1986) bas liquid chromatography support s...

    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 installin...

    Installing the lc-23c in a cc-5 compartment 1. Lower the cc-5 lid and remove the utility cover from the back panel of the cc-5 cabinet (four screws). 2. On some models, pressed-in, threaded nuts will be located on the outside of the back panel (figure 6). These must be removed. Do not remove if they...

    Making plumbing connections for simple arrangements, use the innermost trough of the lc-23c. This location minimizes detector and valve hookup tubing. If you are coupling columns together, the longer trough will be more useful. A special coil of tubing is provided with each lc-23c (see figure 7). At...

    Section 4. Operation for purposes of instruction, we will reference channel 1, although channel 2 is identical. 1. With the heater and probe cables disconnected, turn on the main power to the lc-22c. 2. Rotate the display selector knob to illuminate “set 1" in the red display window. 3. Using the “s...
