￭ Connect the separation column (see Chapter 3.22, page 62)
– Fasten the inlet of the separation column either to the end
of the column inlet capillary or to the guard column (if
used) according to the specifications contained in the leaf-
let accompanying the column.
– Rinse separation column.
– Fasten the MSM-HC capillary labeled with in with a
6.2744.070 PEEK pressure screw at the output of the sepa-
ration column.
10 Conditioning the instrument
See Chapter 4.1, Page 64
The instrument is now ready for measuring samples.
3.3 Installation of the low pressure gradient
The installation of the 850 Professional IC Anion MSM-HC LP Gradient
must be adjusted slightly in order to be operated as a low pressure gradi-
ent system. The following installation instructions list the necessary work
steps in brief. At each step you will find cross-references to more detailed
installation instructions for individual components, should you require
such aids.
Installing the low pressure gradient
1 Expanding the instrument to low pressure gradient
See Chapter 3.11, Page 35
￭ Loosen the 6.1834.090 connection tubing (1-7) from the output
of the eluent degasser.
￭ Dismount the coupling (20-9) and pump head inlet capillary
(20-7) of the high pressure pump.
￭ Connect the 6.2758.020 mixing coil for low pressure gradients
with its short pressure screw directly to the input of the high pres-
sure pump, (see Chapter 3.12.2, page 40) and with its longer
pressure screw to the output of the mixing valve (see "Connecting
mixing coil for low pressure gradients", page 37).
￭ Screw on the 6.1834.120 connection tubing to the output of the
eluent degasser (see "Connecting the eluent degasser", page
34) and connect with input A of the mixing valve (see "Connect-
ing connection tubings", page 38).
