Reactivity-adjusted VOC measurements by Airtrak: a feasibility study

Article Abstract:

A feasibility study on the reactivity-adjusted volatile organic compound (VOC) measurements by the Airtrak instrument is important in understanding the ozone-precursor relationships in urban and rural regions. The Airtrak, which is advertised to continuously measure smog formation coefficients and reactivity-adjusted VOC concentrations in the sampled air, is an integrated air quality assessment instrument that is composed of matched dark and photolytic flow reactors. With the Airtrak device, the study shows that when the airstream contains only VOC and constant concentrations of NO, the relationship between SP (smog produced) and VOC concentrations can be represented by a quadratic polynomial.

Reactivity-adjusted VOC measurements by airtrak: a feasibility study

Article Abstract:

An integrated air quality assessment instrument, Airtrak, was used to measure reactivity-adjusted volatile organic contaminants (VOCs). Results have revealed that the relationship between VOC and smog produced concentrations can be represented by a quadratic polynomial when the airstream contains only VOC and nitrous oxide (NO) and NO concentration is constant.
