2 Installation
Connection to the column
1 Fix the optical unit directly under the column if possible.
Note: Always position the optical unit with the filter wheel cover
facing upwards.
2a Connect the column outlet tubing
directly onto the top (a) of the
optical unit for the 5 mm flow
cell using a fingertight connector.
2b Connect the column outlet tubing
onto the bottom (b) of the optical
unit for the 2 mm flow cell using
a fingertight connector.
Note: The inlet port of the 5 mm UV
cell is above the optical unit. The inlet
port of the 2 mm UV cell is below the
optical unit.
3 Screw to fingertightness.
4 Connect the optical unit outlet tubing onto the opposite hole in
the flow cell. Use fingertight connectors.
If no outlet tubing exists, cut a piece of PEEK tubing (i.d. 0.5
mm, o.d. 1/16”). The length should be 170 mm when using the
5 mm flow cell, and 230 mm when using the 2 mm flow cell.
5 Connect the other end of the tubing to the conductivity flow cell
or to another appropriate unit.
2.4 Installing the conductivity flow cell
1 Place the conductivity cell in its cell holder, or
in a suitable location, as close to the optical
unit/column as possible. The cell can be
placed up to 1.5 m from the monitor housing.
Secure the cell with the clamp.
Note: When the conductivity flow cell is used
in conjunction with the pH electrode, place
the conductivity flow cell and select its flow
direction so that the screw head end of the flow cell faces the
pH flow cell.
2 Connect the conductivity cell to the socket
Conductivity Flow Cell
on the rear panel of the module.
3 Connect the tubing with fingertight connectors.
