• If filter is used, replace it regularly
• Make sure the mounting bracket screws are tight.
• Be sure all cables are securely connected.
• Calibrate the gasifier. The consistent output pressure is critical for reproducible analysis and
accurate quantitation. If your analysis needs be done regularly, it is recommended to verify the
system by using your calibration standard weekly to establish the experimental relative
response factor set. The results should be consistent, otherwise it may indicate there is
pressure drifting and/or your gasifier has leak or block issue. If your test is only done
occasionally, analyze the calibration standard before each set of analysis
