摘要: The chemical amplifier for atmospheric peroxy radical measurements, first described in the early 1980s has been improved relative to these earlier reports. details of instrument and a new calibration procedure are discussed as they relate participation field study southeastern United States summer 1990. theoretical behavior is also examined with use analytical solutions relevant kinetic equations well numerical model. Several issues relevance addressed including response organic radicals, interferences from PAN peroxynitric acid, accuracy, precision, detection limits studied through number laboratory investigations. Some findings realized since 1990 included. 44 refs., 16 figs., 2 tabs.
