2B Technologies is dedicated to the development and commercialization of new analytical instruments for atmospheric and environmental measurements. We specialize in miniaturized instruments for measurements of ozone (O3), nitric oxide (NO), nitrogen dioxide (NO2), mercury (Hg; under development), and other chemical species in air.

Our small, lightweight, low-power instruments are now used for atmospheric measurements using balloons, kites, UAVs, research aircraft, and at many remote sites, including Antarctica, the Galapagos Islands, the Greenland ice sheet, the summit of Mont Blanc, the Amazon rain forest, on buoys in the Arctic Ocean, on commercial airliners, in many U.S. National Parks and at numerous other locations throughout the world.

Model 405 nm NO2/NO/NOx Monitor

Model 405 nm NO2/NO/NOx Monitor

The Model 405 nm provides a direct measurement of NO2 by absorbance of light at 405 nm with a precision of 2 ppb or better. The high precision is achieved by using a White cell with a path length of ~2 m. Other methods such as chemiluminescence require conversion of NO2 to NO using a molybdenum or photolytic converter to measure NOx and then determining NO2 as the difference between NOx and NO. Such methods suffer from inaccuracy due to variations in conversion efficiency and interferences from other compounds that may convert to NO. The Model 405 nm also measures NO by modulating the addition of ozone with ~100% conversion of NO to NO2. NOx is then determined by simply adding NO and NO2. read more

Model 205 Dual Beam Ozone Monitor

Model 205 Dual Beam Ozone Monitor

The Model 205 Dual Beam Ozone Monitor makes use of two detection cells to improve precision, baseline stability, and response time. In the Dual Beam instrument, UV light intensity measurements Io (ozone-scrubbed air) and I (unscrubbed air) are made simultaneously. Combined with other improvements, this made it possible to reduce the time between ozone measurements to 2 seconds, making our instrument the fastest UV-based ozone monitor on the market, while still retaining the small size, weight, and power requirements of our popular Model 202 Ozone Monitor. Fast measurements are especially desirable for aircraft and balloon measurements where high spatial resolution is needed. Alternatively, one can choose to average more points internally to obtain even better precision. Flash card memory and a long-life, quiet internal air sampling pump are now standard on the instrument. The Model 205 Dual Beam Ozone Monitor has been approved by the EPA as a Federal Equivalent Method (FEM) based on a modification of the Model 202: EQOA-0410-190. read more
