2 Connect the electrode cable
• The included 6.2156.000 Cable for connecting the measur-
ing cell is attached to connections 38, 39 and 40 of the
measuring cell using the three connectors 19, 20 and 24
(see Fig. 6).
• The other end of the cable is inserted into connection '1' of
the 817 Bioscan 817 with connector 27 (see Fig 3).
3 Connect the column
• Screw column connection capillary 21 of the column on to
eluent inlet 41 of the flow-through measuring cell using the
6.2744.130 Pressure screw.
4 Connect the waste container
• In order to ensure an adequate backpressure, screw a PEEK
capillary (approx. 1 m) on to eluent outlet 37 of the measuring
cell.
• Lead the end through opening 3 into a sufficiently large waste
container and attach it there.
5 Mount the measuring cell
• Attach the flow-through measuring cell to the holder 22 817
Bioscan which is provided for it (see Fig. 3).
• Rotate the holder and the cell so that the cell outlet is located
as high as possible. In this way it is easier for any air bubbles
that may occur to escape from the cell.
Never switch on the flow-through cell when this is
(a) not being rinsed through with a conducting eluent at the
time,
(b) not completely connected up, or
(c) when its outside is moist so that so a short circuit could
occur between the connections of working electrode 38
and auxiliary electrode 39!
2.3.6 Connecting the waste tubing
The 817 Bioscan has an outlet 13 on its rear panel for discharged
liquids to which the waste tubing can be attached. Proceed as follows:
1 Connect the waste tubing
• Attach matching tubing (e.g. Silicone tubing, optional) into
outlet 13 (see Fig. 2).
2 Lead the waste tubing to a drain
• Place the other end of the waste tubing in a drain and attach
it there.
