1. Definition of new program parameters for the 788 IC Filtration
Sample Processor under Configuration/Control:
FILL A 2 = ---***0*010***
INJECT A 2 = ---***1*000***
ZERO 2 = ---***0*011***

012 Ctrl Init 732
013 Scan Wait1
014 Ctrl FILL A 2
015 Ctrl Init 732
016 Pump 240 s
017 Ctrl INJECT A 2
018 Ctrl Init 732
Initialize remote interface
Move needle to sample position
Place lift with needle to working position
Trigger autozero at 732/1 IC Detector
Switch injection valve A at 733 to "Fill"
Switch 753 suppressor module to next position
Fill sample loop A with sample during 240 s
Switch injection valve A at 733 to "Inject"
Move needle to sample position (+1)
Place lift with needle to working position
Trigger autozero at 732/2 IC Detector
Initialize remote lines at 732/1 and 732/2
Wait until 732/1 IC Det. sends signal on remote line 3
Switch injection valve B at 733 to "Fill"
Initialize remote lines at 732/1 and 732/2
Fill sample loop B with sample during 240 s
Switch injection valve B at 733 to "Inject"
Initialize remote lines at 732/1 and 732/2
3. Definition of new program parameters for the 723/1 IC Detector
under Programm/Remote Configuration:
Start_788 = **1*****
Reset_Start_788 = **0*****
4. To synchronize the second injection to the start of the second
chromatogram, a time program is started for the 732/1 IC Detector
directly with the first injection:
1.0 Start_788
1.1 Reset_Start_788
1.2 Flag end
Both detectors 732/1 and 732/2 are registered in the system window
under Setup/Start mode in the field 'Start with inject' .
4. By this procedure, with a delay of one minute, the 788 IC Filtration
Sample Processor receives a signal for processing the second
sample. The total resulting delay (5 min.) is now independent from
the time the sampler needs for rotating to the next sample.
Therefore, the method for the second sample injection (e.g. method
'cation') gets a start delay under Method Setup/Measure:
Start delay: 5.0 min
