6.5 Valve interfaces
The two valve interfaces 38 38 and 46 46 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
