9.2 Performance Problems
When the response from a span check is outside the control limits, the cause for the drift should
be determined, and corrective action should be taken. Some of the causes for drift are listed
below:
NOTE
It has been our experience that about 50% of all analyzer performance
problems are sooner or later traced to leaks in some part of the system.
1.
Fluctuations in flow. Such as leaks or plugged orifices.
2.
Lack of preventive maintenance.
3.
Change in zero air source.
A.
Air containing NO leaking into zero air line.
B.
Saturation of charcoal and/or Purafil scrubbers.
