Epa Calibration Using Permeation Tubes; Calibration Frequency; Record Keeping - Teledyne 100E Instruction Manual

EPA Protocol Calibration
Cylinders of working gas traceable to NIST-SRM's (called EPA Protocol Calibration Gas) are
also commercially available (from sources such as Scott Specialty Gases, etc.).

8.1.4. EPA Calibration Using Permeation Tubes

T-API does not recommend the use of permeation tubes as a source of span gas for EPA
protocol calibration operations.

8.1.5. Calibration Frequency

To ensure accurate measurements of the SO
time of installation, and re-calibrate it:
• No later than three months after the most recent calibration or performance
audit which indicated analyzer calibration to be acceptable.
• 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.

8.1.6. 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?
