5. Click Send Setup.
6. Click Post Process.
7. Verify that the new chromatograms display correct labels.
To manually label the peaks from the chromatogram view window:
1. Select the desired chromatogram tab.
2. Zoom in on the chromatogram.
a. Place the cursor above the integrated peak area. Right click and hold the mouse button.
b. Drag the cursor across the area to be enlarged.
c. Release the right mouse button. The chromatogram and peak area will be increased.
d. Adjust the size as needed.
3. Place the cursor inside of the peak, right click, and select Label Peak.
4. On the Manual Peak Label window, click Select One. A list of component names displays.
5. On the component name list, locate and click the correct name of the peak.
6. Click Label Peak.
7. Click Send Setup.
8. Repeat steps 3-7 for all peaks requiring a label.
9. Click Post Process. After reprocessing, the chromatogram should display the correct labels.
10. Repeat steps 1-9 for the other chromatogram.
6.6.1.4 Adjust the Forward Flow Duration
A small peak (part of C6+) displaying after the nC5 peak indicates that the Forward Flow is too long.
It may be necessary to shorten the Forward Flow Flow/Inject Time. Make small time increment
changes to this parameter to avoid over-compensation.
Adjust the Forward Flow/Inject Time in the carrier pressure/time parameter area:
1. Select the desired chromatogram.
2. Type a new value for the Forward Flow Flow/Inject Time field.
3. Click Send Setup.
4. Click Run a Single Cycle.
5. Repeat steps 1-3 as necessary. If the Cal Blend component concentrations IC5 and nC5 are
similar, the peak areas should be within 3% of each other. If using ABB's standard blend, IC5
and NC5 are approximately 0.1%.
If water causes a problem, you may need to increase the Backflush/Reverse Time.

Calibrate the analyzer

The analyzer is factory-calibrated and should not require a calibration immediately. It is recommended
the device operate for a period of eight continuous hours before field-calibrating.
Before calibrating, run a manual peak find to verify proper timing and peak assignments (see section
6.6). After calibration, run manual peak find again to verify calibration results.
A calibration cycle includes purge cycles and multiple calibration cycles for averaging. The system
defaults to stream 4 (cal stream), two purge cycles and three calibration cycles.
