850 Professional IC–AnCat – non-suppressed
￭ Place the detectors in the instrument and connect them (see
Chapter 3.6.2, page 22).
￭ Remove transport locking screws (see "Removing transport lock-
ing screws", page 24).
￭ Connect the leak sensor (see "Connecting the leak sensor", page
24).
￭ Connect drainage tubings (see "Installing drainage tubing", page
27).
3 Installing the eluent path
The following steps need to be carried out once for each of the two
channels.
￭ Equip the eluent aspiration tubing and connect with the eluent
bottle (see Chapter 3.8.1, page 30).
￭ At the end of the pre-installed column inlet capillaries (3-2) and ,
respectively (3-5), connect one 6.2744.040 coupling each, using a
6.2744.014 pressure screw, instead of the columns.
￭ Connect detector inlet capillaries (3-3) and, respectively (3-6), to
the 6.2744.014 coupling, using a 6.2744.040 pressure screw.
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.
The following steps need to be carried out once for each of the two
channels.
￭ 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 3.13, page 43).
￭ 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.
￭ In the cation channel, replace the 6.1825.210 sample loop with
the 6.1825.220 sample loop (see "", page 45).
