The peristaltic pumps of the 833 IC Liquid Handling Pump Unit and the
833 IC Liquid Handling Sample Preparation Unit start immediately when
the system is activated (recording the baseline). This is done by
activating the option ’Start pump with startup hardware’ in IC Net for each
instrument.

The program for the 766 IC Sample Processor is as follows:
001 Ctrl INIT 819
002 Move sample
003 Lift work
004 Ctrl ZERO 1
005 Ctrl FILL A 1
006 Pump 120 s
007 Ctrl INJECT
A1
008 Ctrl STEP MSM 833
− Initializes remote lines at 819
− Moves needle to sample position
− Moves lift with needle to working height
− Triggers autozero at 819 IC Detector
− Switches injection valve A at 820 to "Fill"
− Transfers sample to sample loop via sample
preparation module (*)
− Switches injection valve A at 820 to "Inject"
− Switches sample preparation module to next
position
(*) The time for transferring the sample via the sample preparation module must
be adequate, but should be kept as short as possible in order to minimize
contamination of the downstream enrichment column with unwanted anions
from the water used.
