Use of the Flame Photometric Detector Method for Measurement of Sulfur Dioxide in Ambient Air. A Technical Assistance Document.

摘要

This technical assistance document is intended to serve as a source-book of information and outlines of good practice for operation and calibration of ambient air SO2detection analyzers based on the measurement principle of Flame Photometric Detection (FPD). This is accomplished through the identification and control of critical parameters affecting the operation and calibration of FPD analyzers. The document may be used with analyzers which measure total sulfur,as well as with new SO2specific models which have been designated as equivalent methods by EPA. This document is to be used in conjunction with the instrument manufacturer's instruction manual. The document consists of six sections: (1) Introduction to FPD principle, (2) Installation and startup of the analyzer, (3) Calibration sources and their air supplies, (4) Procedures for multipoint dynamic calibration, (5) Procedural aids,and (6) References and Index.
