4 Settings at the 750 Autosampler
• Set parameter " Run time " to 0.0 to activate the external start
of the 750 Autosampler (see section 3.5 of the 750 Instruc-
tions for Use). Filling the sample loop of the injection valve
only takes place when the impulse produced by the 761
Compact IC at remote output 3 (see point 5) makes contact
at the "EXTERNAL INJECT INPUT" of the 750 Autosampler.
The run time will then be determined externally.

• A time program must be drawn up for the selected system
which first switches the injection valve to the "Fill" position,
then produces an impulse at remote lead 3 to start sample
addition by the 750 Autosampler and finally switches the in-
jection valve to the "Inject" position. The following example
shows such a program:
2.10.2 Connection of the 766 IC Sample Processor
The 766 IC Sample Processor available from Metrohm as an option is
an automatic sampler for ion chromatography. It accommodates max.
127 samples each of 2.5 mL or 11 mL, which are automatically trans-
ferred to the sample loop attached to the injection valve of the 761
Compact IC. Sample changing and filling the sample loop are started
by a remote signal produced by the 761 Compact IC (761 Compact IC
as "Master").
The 6.2141.110 Cable is required for connecting the 766 IC Sample
Processor. The 766 IC Sample Processor is connected to the 761
Compact IC as follows:
1 Electrical connection 761 – 766
• Connect the end of the 6.2141.110 Cable marked with "766"
to the remote interface 22 of the 766 IC Sample Processor
(see 766 Instructions for Use).
