Sample Processing Events (Default)
The following events occur if samples are processed using the default
control program created with the Program Wizard:
• The pump is turned on.
• If an AS40 autosampler is being used, the AS40 load cycle is started.
If no autosampler is being used, the program pauses for you to
manually load the sample into the sample loop.
• After the AS40 load cycle is complete or you manually load the
sample, the background conductivity is offset from the total, thereby
zeroing the baseline conductivity value.
• The injection valve position is switched to the Inject position.
• Data acquisition is turned on.
• The injection valve returns to the Load position after 1 minute.
• Data acquisition is turned off after 30 minutes.
3.5.6 Sample Injection
There are three ways to inject sample into the ICS-90: via syringe,
vacuum syringe, or autosampler.
Injection via a Syringe
1. Make sure the injection port on the ICS-90 front door (see Figure 2-1)
is connected to the sample port S (5) on the injection valve (see
Figure 3-4
).
2. Fill the 1 cc syringe (P/N 016388) provided in the ICS-90 Ship Kit
(P/N 059947) with a calibration standard or sample.
3. Insert the syringe into the injection port on the ICS-90 front door.
4. Overfill the sample loop with several sample loop volumes. Excess
sample will exit through the injection valve waste line.
5. Leave the syringe in the port.
