2. Fill the 1 cc syringe (P/N 016388) provided in the ICS-2000 Ship Kit
(P/N 064375) with a calibration standard or sample.
3. Insert the syringe into the injection port on the ICS-2000 front door.
4. Verify that the injection valve is in the Load position.
5. Overfill the sample loop with several sample loop volumes. Excess
sample will exit through the injection valve waste line.
6. Leave the syringe in the port.
7. Switch the injection valve to the Inject position (see Section 3.10.4 ).
3.10.2 Loading Samples with a Vacuum Syringe
1. Disconnect the waste line from port
W (6)
of the injection valve (see
Figure 3-12 ) and attach a shorter line: 25 to 30 cm (10 to 12 inches) of
PEEK or Teflon® tubing.
2. Place the free end of the line into the sample.
3. Verify that the injection valve is in the Load position.
4. Insert the 1 cc syringe (P/N 016388) provided in the ICS-2000 Ship
Kit (P/N 064375) into the injection port on the ICS-2000 front door
(see
Figure 2-1 ) and pull out the plunger to draw the sample into the
injection valve.
5. Switch the injection valve to the Inject position (see Section 3.10.4 ).
3.10.3 Loading Samples with an Autosampler
1. Verify that the autosampler output line is connected to port
S (5)
of the
ICS-2000 injection valve.
2. Prepare and fill the sample vials and place them in the autosampler
tray or cassette. Refer to the autosampler manual for detailed
instructions.
3. The sample loading process depends on the autosampler. Refer to the
autosampler manual for detailed instructions. In general, use one of
the following methods:
•
Include the commands for controlling sample loading in a
Chromeleon program. See the examples in
Section 3.10.5 .
