2.5 Connection of devices
The 858 Professional Sample Processor, the 850
Professional IC AnCat system and the 797 VA Computrace
are connected with each other via the 800 Dosino with a 10
mL Dosing Unit mounted on the 858 Professional Sample
Processor.
Connect the sample needle to Port 3 of the 10 mL Dosing
Unit at the 800 Dosino using a PEEK capillary (70 cm,
d=0.75 mm, 6.1831.070). The 850 Professional IC AnCat
system is connected to the Dosing Unit at Port 1 using a
PTFE capillary (90 cm, d=0.25 mm, part of 6.1803.150). The
sample inlet capillary (PEEK, 90 cm, d=0.5 mm, part of
6.1822.410) of the 797 VA Computrace is connected to the
Dosing Unit at Port 2. Port 4 of the Dosing Unit is equipped
with an adapter (6.1808.280) and a FEP tube (6.1805.530)
and connected to the waste.
The second 10 mL Dosing Unit with an 800 Dosino is
connected to one capillary of the fourfold micro tip and is
used to dilute the sample for the VA measurement
automatically (solution j).
