EPA Protocol Calibration Teledyne API - T100 UV Fluorescence SO2 Analyzer

10.1.5. CALIBRATION FREQUENCY
To ensure accurate measurements of the SO
2
concentrations, calibrate the analyzer at the
time of installation, and re-calibrate it:
No later than three months after the most recent calibration or performance audit to
indicate an acceptable analyzer calibration.
An interruption of more than a few days in analyzer operation.
Any repairs which might affect its calibration.
Physical relocation of the analyzer.
Any other indication (including excessive zero or span drift) of possible significant
inaccuracy of the analyzer.
Following any of the activities listed above, the zero and span should be checked to
determine if a calibration is necessary. If the analyzer zero and span drifts exceed locally
established calibration units or the calibration limits in Section 2.0.9, Subsection 9.1.3
(Q.A. Handbook), a calibration should be performed.
10.1.6. RECORD KEEPING
Record keeping is a critical part of all quality assurance programs. Standard forms
similar to those that appear in this manual should be developed for individual programs.
Three things to consider in the development of record forms are:
Does the form serve a necessary function?
Is the documentation complete?
Will the forms be filed in such a manner that they can easily be retrieved when
needed?
