850 Professional IC–Anion – MSM-HC – MCS – LP Gradient
2 Installations on the rear of the instrument
￭
Remove handle and rollers (see Chapter 3.7.1, page 22) .
￭
Place the detector in the instrument and connect it (see Chapter
3.7.2, page 25) .
￭
Remove transport locking screws (see "Removing transport lock-
ing screws", page 27) .
￭
Connect the leak sensor (see "Connecting the leak sensor", page
27) .
￭
Connect drainage tubings (see "Installing drainage tubing", page
30) .
3 Installing the eluent path
￭
Equip the eluent aspiration tubing and connect with the eluent
bottle
(see Chapter 3.9.1, page 33) .
￭
Instead of the column, connect the 6.2744.040 coupling with a
6.2744.010 pressure screw at the end of the pre-installed column
inlet capillary.
￭
Use a 6.2744.014 pressure screw to connect the capillary of the
MSM-HC labeled with
Eluent to the other end of the 6.2744.040
coupling.
￭
Use a 6.2744.090 long pressure screw to connect the capillary of
the MSM-HC labeled with
Detector to the input of the MCS (see
Chapter 3.20.2, page 63) .
￭
Connect the detector inlet capillary with a 6.2744.090 long pres-
sure screw to the output of the MCS
(see Chapter 3.20.2, page
63) .
4 Installing the sample path
NOTE
The sample degasser does not have to be connected. We recom-
mend the usage of the sample degasser only if the sample matrix
requires it.
￭
Connect the 6.1803.040 sample aspirating capillary (3- 8 ) connec-
ted at the sample input of the injection valve to the output of the
sample degasser with the aid of a 6.2744.090 long pressure
screw
(see Chapter 3.15, page 48) .
￭
Connect a part of the 6.1803.040 sample aspirating capillary with
a 6.2744.090 long pressure screw to the input of the sample
degasser. Guide the other end out of the instrument through a
capillary feed-through.
