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***

 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
