Techniques for Continuous Monitoring of Hydrocarbons

Abstract
Among the present methods for analyzing hydrocarbons to perform ambient air, stationary source, and vehicular emission monitoring are flame ionization detection, gas chromatography, nondispersive infrared spectroscopy, dispersive infrared spectroscopy, and catalytic oxidation. Promising methodology includes ultraviolet spectroscopy, optoacoustic detection, along with others. Problems associated with the production of improved instrumentation are discussed and recommendations made for further research and development.
