2. Perform Test Procedure 30 (Checking Temperature Table Values) and Test Procedure 9
(Baseline Cyclic Carrier Regulator), as applicable.
TP 11: COMMON USAGE OF GASES
1. Are other analyzers serviced from the same burner air, carrier, or burner fuel source,
experiencing noise? If Yes, then the noise problem is most likely related to a common utility gas,
tubing, fitting, or regulator.
2. Perform Test Procedure 12 (Utility Gas Contamination Procedure).
TP 12: UTILITY GAS CONTAMINATION PROCEDURE
1. Verify Burner Fuel is UHP Hydrogen (FID or FPD). If not, replace hydrogen cylinder with UHP
Hydrogen. If noise is eliminated, this test is completed. If noise is still present, continue to step
2.
2. Verify carrier purity. If purity questionable, replace carrier gas cylinder. If noise is eliminated, this
test is completed. If noise is still present, continue to step 3.
3. Replace burner fuel cylinder (FID or FPD). If noise is eliminated, this test is completed. If noise is
still present, continue to step 4.
4. Replace carrier or burner fuel cylinder regulators. If noise is eliminated, this test is completed. If
noise is still present, continue to step 5.
5. Replace or wash tubing from cylinder regulator to analyzer.
6. Disassemble and clean Detector (see “FID REPAIR/Cleaning the Collector” in Section 8).
TP 13: BURNER AIR CATALYTIC CLEANUP UNIT
1. Determine if air cleanup unit is operational and at operating temperature. Perform Test
Procedure 30 (Checking Temperature Table Values), steps 1 to 3, 8 and 9.
2. If available, connect high purity bottled air to burner air connection. If noise disappears, see
“METHANIZER/AIR CLEANUP REPAIR” in Section 8.
3. If bottled air is not available, see “METHANIZER/AIR CLEANUP REPAIR” in Section 8.
TP 14: COAXIAL CABLE
CAUTION
It is the customer’s responsibility to ensure that the area is safe and and hazard-
free, and will remain so the entire time the analyzer is open. This responsibility
includes ensuring adequate ventilation in analyzer shelter and obtaining proper
work permits, etc.
See "AIR PURGING" in Section 4 for the override function. Do not perform
override until you have read Section 4 completely and you understand and can
perform the procedure requirements.
1. Open isothermal oven door.
