SERVOPRO CHROMA Gas Analyser
112 04400001A / Revision 7
9. Power on the analyser.
10. Verify that analyser parameters are as reported in the Test Results Sheet (TRS)
shipped with each analyser.
11. Verify flow is coming out of the carrier and detector vents and adjust carrier gas
supply pressure to have a total flow close to the one specified in the analyser
TRS.
12. Verify leak integrity of the external system using a gas leak detector.
CAUTION
Do not use SNOOP to find leaks as it can contaminate the gas lines. Use a
gas sniffer.
13. Set oven set point to 200 degC and purge the analyser for 12 hours minimum.
14. After the purge, return the oven set point to the original value, recorded in the
analyser TRS.
15.
For PED
: V
erify analyser “Detector A” raw signal for p
urity and compare to
data recorded on analyser TRS. This must be done with all chromatographic
valves in the off state. All “Detectors A” are specific to nitrogen. A reading
above 0.10 V for helium carrier and 0.15 V for argon carrier with 65% plasma
power indicates a leak in the system.
16.
For FID
: Start up the detector as described in Section 12.9.
17. For TCD , continue to next step.
18. To validate the chromatography, inject the calibration gas. Make sure that all
peaks are centred in their peak window. If not, adjust the peak windows. Refer
to section 4.6.4.
19. After chromatography validation, calibrate the analyser (see Section 4.7). Then,
run the analyser continuously on calibration gas for 12 injections. Verify that
the last 4 results are within repeatability specification. Compare with results
from the analyser Test Results Sheet (TRS).
20. Inject the process gas continuously and monitor the results. Make sure peak
baselines are correct and that readings are stable.
