3.5 The Metrohm IC control software
To use the 813 Compact Autosampler with a 761 Compact IC or
a 7 90 Personal IC one has to create a time program. First of all the
IC has to send a Remote signal (Remote line 3) to synchronize
the command sequence (first Remote signal) of the 813 Compact
Autosampler. After that the injection valve is switched to 'Fill' posi-
tion. Th en a second Remote signal starts the filling of the sample
loop. The pump duration for filling the sample loop is defined by
the third Remote signal. After sending this Remote signal the in-
jection valve is switched to 'Inject' position immediately which
starts the data aquisition. During sample injection the peristaltic
pump of the 813 Compact Autosampler is still running. 12 s after
receiving the Remote signal the Autosampler will stop the pump.

3.5.1 Operational conditions
To ensure a correct interconnection (Autosampler – Ion chro-
matograph), the following conditions must be met:
• When the Ion chromatograph is operational the 813 Com-
pact Autosampler hast to be started before the 'Sample
Queue' of the IC.
• When using the 761 Compact IC the initial state of the Re-
mote line 3 has always to be set to 0 (set System startup val-
ues : Remote line 3 = 0 ).
