1 Check mounting screws
Caution
Avoid overtightening the mounting screws (1-6), as this could
damage the distance piece (1-7)!
￭ Use the provided hexagon key (6.2621.150) to loosen all four
mounting screws (1-6) by one rotation.
￭ Then slighly tighten the screws again, e.g. by holding the hexagon
key between index finger and thumb only.
￭ Finally, tighten all four mounting screws by a quarter rotation.
Always tighten opposing screws, i. e. tighten one screw antd then
its opposite.
2 Connect the electrode cable
￭ Attach the electrode cable (6.2156.000 delivered with the 871
Advanced Bioscan) to the working electrode connection (1-4)
(red), the reference electrode connection (1-1) (black), and the
auxiliary electrode connection (1-3) (blue) of the flow cell.
￭ Attach the other end to the connection for electrode cable of the
871 Advanced Bioscan.
3 Connect the separating column
￭ Use a pressure screw (6.2744.130) to screw the column connec-
tion capillary of the separating column to the inlet for eluent
(1-2). Push the connection capillary into the inlet as far as it will
go (approx. 1.5 cm) and then fix it with the pressure screw (this
will prevent dead volume).
4 Connect waste tubing
￭ To ensure sufficient back pressure, connect a PEEK capillary
(6.1831.010) of approx.1m length to the outlet for eluent (1-5).
Push the PEEK capillary into the outlet as far as it will go (approx.
0.5 cm) and then fix it with a pressure screw (6.2744.130) (this
will prevent dead volume).
￭ Place the other end of the PEEK capillary into a waste container
and attach it.
