The three 60 cm FEP tubing connections (6.1850.060, supplied with 815) are used to connect
membrane pump 1 / tower 1 of the 815 and the three rinsing nozzles (6.2740.020, supplied with
815) to openings 2, 5 and 7 of the external cell (see page 7 and 11, chapter 5.1).
The 60 cm M8 PTFE tubing connection (6.1805.510) is used to connect membrane pump 1 / tower
2 of the 815 and the M8 PTFE aspiration tip (6.1543.170) to opening 1 of the external cell (see
page 7 and 11, chapter 5.1).
The two buret tips (6.1543.080) are each attached by a stopper (6.2730.030) to the titration head
(6.1462.070).
The two 80 cm FEP tubing connections (6.1850.110) are used to connect the buret tips
(6.1543.200) at the titration head (6.1462.070) and port 2 of the 10 mL and 50 mL Dosing Units.
The 60 cm FEP tubing connection (6.1850.060) is used to connect port 4 of 50 mL Dosing Unit and
opening 9 of the external cell (see page 7).
The 40 cm FEP tubing connection (6.1850.100, supplied with 807) is used to connect port 4 of the
10 mL Dosing Unit and the M6 opening of the eluent bottle attachment (6.1602.160); the FEP
aspiration tubing (6.1829.010, supplied with 807) should previously have been inserted. The
absorber tube (6.1609.000) is filled as usual with lime and cotton wool and inserted into the
opening provided for it in the eluent bottle attachment in order to protect the nitric acid from CO
2
.
The 40 cm FEP tubing connection (6.1850.100, supplied with 807) is used to connect port 1 of the
20 mL Dosing Unit and the buret tip in opening 3 of the external cell (see page 7).
The three 150 cm FEP tubing connections (6.1805.030) are connected to port 1 of the 10 mL and
the 50 mL Dosing Units, as well as port 3 of the 20 mL Dosing Unit; all three tubing connections
are then connected to the 10 L PE waste canister (6.1621.000).
Suitable lengths of the 0.97 mm PTFE capillary (6.1803.020, supplied with 861) are used to
connect port 3 of the 10 mL and the 50 mL Dosing Units (using the screws 6.2744.080 and
6.2744.070) and the injection valves of the two 861 Advanced Compact IC (position 1). The 10 mL
Dosing Unit must be connected to the 861 Advanced Compact IC for cations (2.861.0010) and the
50 mL Dosing Unit to the 861 Advanced Compact IC for anions (2.861.0020).
