The document is the result of a twelve month, three-phase investigative program with the intent of providing EPA with sufficient information to permit the establishment of minimum specifications for the design of continuous extractive sample interface systems. An extractive sampling interface system is the equipment associated with an instrumental source measurement system which extracts, transports, and conditions a sample of the source effluent. The work in this program was directed toward an investigation of interface systems for use on Category I sources for the following instrumental techniques: (1) non-dispersive infrared analyzers, (2) ultra-violet analyzers, (3) electrochemical sensors, and (4) chemiluminescent analyzers. Both laboratory and field results are reported.
