5. Change this program for 'start-dialysis.smt' as follows and save it
again:
001 Ctrl INIT 732
002 Move sample
003 Lift work
004
Ctrl PUMP 754 on
005 Wait 120 s
006 Ctrl FILL B 1 / STEP
007 Wait 540 s
008 Ctrl STEP MSM 753
009 Ctrl ZERO 1
010 Wait 60 s
 Initialize remote lines at 732 detector
 Move needle to sample position
 Place lift with needle to working position
 Start 754 Pump Unit
 Rinse dialysis cell with sample solution
 Stop of acceptor solution
 Dialysis time
 Switch 753 suppressor module to next position
 Trigger autozero at 732 IC Detector
 Additional dialysis time (total 600 s)
End-Dialysis.smt
6. Open system file 'dialysis.smt', again. Select Control/Connect to
Workplace and save it under the new name 'end-dialysis.smt'.
7. Change the program for 'end-dialysis.smt' as follows and save it
again:
001 Ctrl FILL A 1
002 Ctrl INJECT B 1
003 Wait 30 s
004 Ctrl INJECT A 1
005 Ctrl PUMP 754 off
 Switch injection valve A at 733 to "Fill"
 Transfer acceptor solution to sample loop
 Fill sample loop with acceptor solution for 30 s
 Switch injection valve A at 733 to "Inject"
 Stop 754 Pump Unit
8. The sample queue then contains the following entries, for example:
System Ident Vial Chrom. No. Dialysis No.
1 start-dialysis.smt Probe 0 1 - 1
2 dialysis.smt Probe 1 1 1 2
3 dialysis.smt Probe 2 2 2 3
4 dialysis.smt Probe 3 3 3 4
5 dialysis.smt Probe 4 4 4 5
6 dialysis.smt Probe 5 5 5 6
7 end-dialysis.smt Probe 6 6 6 -
This example describes the processing of a queue with six samples.
The columns 'Chrom. No.' and 'Dialysis No.' are just given for
information. Please note that in the 788 program of 'dialysis.smt' not the
given sample position 'Vial' is used; it is increased by 1 to start dialysis
of the next sample. Therefore, all samples have to be arranged on the
sample rack in a closed line.
