Measurements Of Sensitivity For Different Peroxy
Radicals Of The "Chemical Amplifier" Technique
Author(s)
Ole Saastad and Jens Hjorth
Abstract
The "Chemical Amplifier' technique for measurement of peroxy radicals in air is based on
measurement of NO] generated by a chain reaction initiated by peroxy-radicals. The response
of the method to a series of n-alkyl peroxy radicals has been tested in the laboratory. For the
peroxy-alkyl radicals in the range C| to Cs. a decreasing signal was found for increasing
number of carbon atoms.
1 Introduction
Organic peroxyradicals (ROi*) and hydro-peroxyradicals (HO?*) are
key intermediates in the atmospheric oxidation of hydrocarbons and other
volatile organic compounds (VOC). Reaction of OH with VOCs and CO leads
to the formation of these peroxy radicals which, in turn, form also the
corresponding alk
