Determination of halogenated hydrocarbons by flow injection ozone chemiluminescence Original Research Article

A flow injection gas phase chemiluminometer has been constructed for monitoring halogenated compounds which upon UV radiation consume ozone. The ozone concentration is followed by the ethylene–ozone chemiluminescent reaction and by UV absorption. The sensitivity depends on the ability of each compound to consume ozone and the limits of quantification vary from 9.6 and 25 nmol for CFCl3 and CF2Cl2 to 22.5 and 17.2 μmol for CHCl3 and CH3CCl3, respectively.
