7.5 Installation of Other Capillaries
When using other monitors (e.g. UV monitors), the Radioactivity Monitor
should always be the last link in the chain
.
17.
Only with solid cells:
Connect the inlet capillaries as required by your measuring setup to the
column or other monitors, respectively.
18.
Only for admixture cells: (see also Figure 15)
a)
Take the scintillator pump LB 5035 into operation: Connect the capillaries
and supply the scintillator as described in chapter 0, page 38 et seqq.
b)
Connect the capillary coming from the scintillator pump to the T-mixer:
Open screw on T-mixer and take out jam cone, then push capillary through
screw and jam cone, with the screw thread and the tapering end of the jam
cone facing the T-mixer. Push capillary through so that it projects by about
2 - 3 mm on the other end, insert it into the T-mixer and fasten the screw.
Tighten the screw fitting only so much that the connection is leak-proof.
In the same manner, fix the capillary coming from the column, the UV de-
tector or the Analytic Splitter (AS xx) to the other inlet of the T-mixer.
c)
Installation of the Analytic Splitter: see Chapter 5.2, page 46.
Note:
With short and open capillaries or when using plastic capillaries, a stainless
steel capillary of at least 10 cm length should be used between cell con-
nection and open end. Wind the capillary piece around an object of ca. 10
mm
(e.g. ballpoint pen) two times or 4
– 5 times bend in an angle to
protect it against incident light.
