2.11 Connection of external devices
2.11.1 Connection of the 838 Advanced Sample Processor
The 838 Advanced Sample Processor, which is optionally available
from Metrohm, is an automatic sampler for ion chromatography. The
838 Advanced Sample Processor (RS232 interface) is connected to the
PC. The control programs are drawn up in the «IC Net» software. In
order to synchronize program sequences the 838 Advanced Sample
Processor and the 844 UV/VIS Compact IC are connected via the
6.2141.190 Remote cable.
Proceed as follows (after the connection of the 844 UV/VIS Compact
IC):
1 Electrical connection 838 – PC
• Connect the RS232 interface of the 838 Advanced Sample
Processor to a serial COM interface of the PC using a
6.2134.100 Connection cable(9-pin/9-pin).
2 Electrical connection 844 – 838
• Connect Remote connection 23 of the 844 UV/VIS Compact
IC and the Remote connection of the 838 Advanced Sample
Processors using a 6.2141.190 Cable (see 838 Instructions
for Use).
3 Tubing connection 838 – Injection valve
• Screw off aspirating tubing 41 from injection valve 46/60.
• Cut the PEEK capillary tubing mounted on the 838 Advanced
Sample Processor to the required length (so that it can be
connected to injection valve 46/60 of the 844).
• Pull the free end of the PEEK capillary tubing through one of
the openings of the 844 UV/VIS Compact IC and use a
6.2744.010 PEEK Compression fitting to screw it onto
injection valve 46/60.
4 Tubing connection Injection valve – Waste
• Loosen connection capillary 33 from injection valve 46/60
(sample outlet).
• Cut a piece of 6.1831.060 PTFE capillary (sample changer
accessory) to the required length, attach it to injection valve
46/60 using a 6.2744.010 PEEK compression fitting and
place the other end in a waste container.
