Controlling an ICS-90 Ion Chromatography SystemIC Control
Controlling an ICS-90 Ion Chromatography System
Commands for controlling the ICS-90 can be included in a Program (see the examples below), or executed directly from either the Control Panel or the Commands dialog box (select Command… on the Control menu). For a list and description of the commands used most often, refer to Commands for Controlling Dionex Devices 
ICS-90 Chromatography System. Also see the Commands dialog box for a complete list of commands.
The following programs are created with the Program Wizard (see The Control Program The Program Wizard). They are identical, except for the method used to load the sample loop.
Program for an ICS-90 connected to an AS40 autosampler:
|
|
Pump = On |
|
|
|
MeasuredFlowRate |
= 1 |
|
|
;Record the flow rate set from the hardware |
|
|
|
Pressure.LowerLimit |
= 0 |
|
|
Pressure.UpperLimit |
= 3000 |
|
-2.000 |
Pump_ECD_TTL_1. 0v |
Duration= |
|
|
;Turn on TTL 1 for 120 seconds, |
|
|
0.000 |
Pump_ECD.Autozero |
|
|
|
InjectPosition |
Duration= |
|
|
;Set the injection valve to the inject position ;for 60 seconds |
|
|
|
ECD_1.AcqOn |
|
|
30.000 |
ECD_1.AcqOff |
|
|
|
End |
|
Note:
The program above assumes that the ICS-90’s TTL output is connected to the AS40’s Load Relay. Refer to the ICS-90 and AS40 operator’s manuals for connection details.
Program for manual injections:
|
|
Pump = On |
|
|
|
|
MeasuredFlowRate |
= 1 |
|
|
|
Pressure.LowerLimit |
= 0 |
|
|
|
Pressure.UpperLimit |
= 3000 |
|
|
0.000 |
Pump_ECD.Autozero |
|
|
|
|
Message "Manually inject the sample and click OK to continue. If you are using an autosampler remove this command from the Program file." |
;Pause the program and display the message |

Duration= |
|
|
|
ECD_1.AcqOn |
|
|
|
30.000 |
ECD_1.AcqOff |
