Technology Marketing SummaryThe technology can be used to build an apparatus for the measurement of the elusive hydroperoxyl radicals in atmospheric samples. DescriptionThe atmospheric sample is treated with a liquid phase scrubbant to produce a liquid phase atmospheric sample which is subsequently reacted with the luminescent reagent and quantified using a chemiluminescent detector. BenefitsThe technique is simple, inexpensive and provides direct quantitative measurements. Applications and IndustriesIndustries which make air quality products for monitoring health and environment will find immediate use of our technology.

Quantitative determination of atmospheric hydroperoxyl radical
A method for the quantitative determination of atmospheric hydroperoxyl radical comprising: (a) contacting a liquid phase atmospheric sample with a chemiluminescent compound which luminesces on contact with hydroperoxyl radical; (b) determining luminescence intensity from the liquid phase atmospheric sample; and (c) comparing said luminescence intensity from the liquid phase atmospheric sample to a standard luminescence intensity for hydroperoxyl radical. An apparatus for automating the method is also included.
