5.5.4 Analyzer Troubleshooting Guide
A process gas chromatograph can operate properly only if flows are balanced and constant, the
temperature is constant, no leaks are present, and the GC Controller is correctly timed. Before going
through the troubleshooting procedures, perform the routines of the Analyzer Maintenance Checklist.
Checklist records performed regularly may indicate problems and prevent any sudden breakdown.
Do not adjust any values if they are within the nominal tolerance values on the Checklist. Compare
the values with those obtained in preceding weeks. This may pinpoint your problem immediately.
The following is a guide for troubleshooting if a problem with sample analysis occurs. Table 5-2
is a Troubleshooting Checklist to obtain data for a problem diagnosis. This data will be useful if it
becomes necessary to call the Daniel Measurement Services (DMS), a division of Emerson Process
Management, for assistance.
5.5.4.1 Flow Balance Check
a. Ensure that the flow panel gauge is properly set. Refer to the Analyzer Maintenance
Checklist for values. Do not adjust; check with Daniel Measurement Services (DMS), a
division of Emerson Process Management, if your reading is abnormal.
b. Check flow at the measure vent and sample vent (see Troubleshooting Checklist).
5.5.4.2 Temperature
Ensure that the temperature is constant in both the Analyzer and Sample Conditioning System (SCS)
oven (refer to paragraph 5.5.7).
