WebJun 28, 2000 · The flowing afterglow of a microwave discharge can be used to efficiently inactivate bacterial spores. We have conducted a parametric study of the operating conditions of such a system, which shows that the species participating in the killing of spores are oxygen atoms and ultraviolet (UV) photons. The oxygen atoms and the … Flowing-afterglow mass spectrometry (FA-MS), is an analytical chemistry technique for the sensitive detection of trace gases. Trace gas molecules are ionized by the production and flow of thermalized hydrated hydronium cluster ions in a plasma afterglow of helium or argon carrier gas along a flow tube … See more Over the years many variations of the instrument have been made. In the beginning during the 1960s there was the study of flowing afterglow plasma. This study was done by Eldon Ferguson, Art Schmeltekopf and … See more Trace gas analysis One of the first papers reporting the use of the flowing afterglow studied ion-molecule reactions pertinent to the Martian atmosphere. This flowing afterglow technique replaced the then standard stationary afterglow … See more • Charles H. DePuy (chemist) • Robert R. Squires See more tsconfig typeroots
Physics:Flowing-afterglow mass spectrometry - HandWiki
WebA flowing afterglow system has been used to measure the gas-phase, thermal-energy rate constants for reactions between a variety of ions and water-vapour molecules at 300K. A method of measuring water-vapour flow-rates has been developed which may be readily extended to other vapours. Rate constants, together with WebMay 23, 2024 · Afterglow. Afterglow can be defined as a blissful period of mental and physical relaxation after orgasm during which a person enjoys the rush of endorphins … WebFlowing afterglow mass spectrometry, FA-MS, is a sensitive and quantitative mass spectrometry analytical approach that offers a route to on-line, real-time deuterium abundance measurements in water vapour in breath and above aqueous liquids, including urine and serum.
