Round-the-clock, on-line and cryogen-free monitoring of hydrocarbons from acetylene to trimethylbenzene in ambient air
Application Note 016
The presence of volatile hydrocarbons in urban atmospheres is believed to contribute to the formation of ground-level ozone, one of the main constituents of urban smog. The compounds of interest range in volatility from acetylene (ethyne) to trimethylbenzene, and are generally referred to as ‘ozone precursors’.
This application note describes validation of a thermal desorption system for on-line monitoring of a complex mix of volatile and very volatile hydrocarbons (‘ozone precursors’) in air.
