A -- SPECTROMETER FOR SMOG CHAMBER MEASUREMENTS SOL RFQ-OH-98-00058 POC Kathleen Roe, phone (513)487-2144, fax (513)487-2107 WEB: Office of Acqiuisition Management -- Cincinnati Contracts Management Division, The RFQ will not appear on the web site.. E-MAIL: U.S. EPA -- Cincinnati Contracts Management Division, roe.kathleen@epamail.epa.gov. The U. S. Environmental Protection Agency (EPA) National Exposure and Research Laboratory has a requirement for a Spectrometer for Smog Chamber Measurements. The contractor shall provide an instrument that will be used to continuously monitor the concentrations of several atmospheric chemical species produced during smog chamber experiments of atmospheric photochemistry. These compounds are present in the gas phase with nominal concentrations in the 0.1-100 ppb range. The compounds and their concentration measurement requirements include nitrogen dioxide (1-100 ppb), ammonia (1-100 ppb), nitrous acid (0.5-50 ppb), nitric acid (1-250 ppb), formaldehyde (1-100 ppb), carbon monoxide (0.05-50 ppm), and hydrogen peroxide and organic hydroperoxides (1-100 ppb). Measurement approach is not particularly important. The instrument shall be sensitive for each species over the given concentration range, and linear over at least two orders of magnitude. The instrument shall be free from major interferences such as ozone, NOx, organics, etc. A continuous monitoring method is required. The instrument shall provide a maximum flow rate of not greater than 5 Lpm. The instrument shall be able to fit in a laboratory with a smog chamber, requiring a maximum footprint of 3 feet by 5 feet. The instrument shall be flexible to the degree that it shall be capable of measuring other important atmospheric species at their atmospheric concentrations, beyond the required list of compounds, either as delivered or with minor, future modifications. The instrument shall be movable between laboratories, although it does not have to be field rugged. The contractor shall provide warranty, installation, training and documentation in accordance with the specifications/statement of work. It is anticipated that the RFQ will be issued on or about February 19, 1998. Interested vendors may request a copy of the RFQ in writing via e-mail or facsimile. (0034)
