Atmospheric measuring device for understanding smog formation
Date:11/19/2007

these have been cumbersome and costly. The new device is comparatively small, lightweight, and inexpensive, has low power requirements, and gives a sensitive, fast response. It works by detecting a "glowing" signal from a chemiluminescent compound - similar to the compound that makes fireflies glow - when it reacts with the hydroperoxyl radicals in atmospheric samples fed into the device during flight.

"The chemiluminescence produced in solution creates a strong and readily detectable signal without the need for complex amplification procedures," said Lloyd.

The device has been tested in a mountaintop setting, but has not yet been deployed on an aircraft for a sampling mission. It is designed to be flown on atmospheric sampling aircraft, such as the Department of Energy's Gulfstream 1, which has been used by Brookhaven and other national laboratory scientists for a variety of atmospheric studies.
