SECTION 7. TEST PROCEDURES
TP 1: CARRIER, MAKEUP AND UTILITY GAS SUPPLIES
If you suspect a gas supply (flame, fuel, air) problem, perform the following test.
1. Stop Analysis at end of current analysis, and make no sample injection until procedure is
completed.
2. Check gas supply pressures at the analyzer pressure gauges or EPC screens. Pressure
indications should indicate normal operational values as indicated on the application data sheets
or last valid record.
3. If values are low, check gas supply at source gauges. Verify gas cylinder valve(s) are open and
that gas cylinder regulator(s) are adjusted for the correct outlet pressure. Verify isolation valves
which supply carrier or makeup gases to the analyzer are open. Verify the cylinder gas supply is
not depleted. Make necessary adjustments and replace empty gas cylinders with full ones.
4. Check the inlet filter or restrictor to ensure it is not plugged.
NOTE
Gas pressures include all carrier, hydrogen fuel, burner air and utility air supplies.
TP 2: CARRIER AND MAKEUP GAS FLOW ADJUSTMENTS
CAUTION
When the carrier supply is turned on, if there is no pressure indicated on the
carrier gauge, do not increase carrier flow. Leak check every connection outside
the analyzer on the entire carrier flow path.
Ensure adequate ventilation in analyzer shelter.
1. Stop Analysis at the end of the current analysis and make no injection until procedure is
completed.
2. (FID or FPD) Extinguish flame by removing burner air and fuel.
3. Refer to the application data sheets supplied with your analyzer and verify correct reference and
column carrier flow rates, correct hydrogen fuel and burner air flow rates (if FID or FPD), correct
splitter adjustment, and correct air pressure adjustments.
4. (TCD) Make necessary adjustments and balance detector using Test Procedure 5 (TC Detector
Balance).
5. (FPD) Make necessary adjustments using Test Procedure 43 (FPD Gain Setting).
TP 3: SAMPLE VALVE LEAKING/COLUMN FLOODING
WARNING
Sample will spill or leak out during this procedure. Consult MSDS sheets on file at
your location for safety requirements.
