6.5 Valve interfaces
The two valve interfaces 3838 and 4646 of the 733 IC Separation Center can
be used for the attachment of external devices (e.g. 750 Autosampler,
«IC Metrodata for Win95») which can be employed to control the injec-
tion valves or the suppressor module (see section 2.3). The two valve
interfaces for the injection valves A and B (or the suppressor module)
are identical and have the following connections
