The solicitation will be posted on or after July 29, 2013 in Fedconnect. Only vendors registered in Fedconnect will be able to submit a quotation. NAICS Code: 334516 Gas analyzers, Analytical Laboratory Instrument Manufacturing The U.S. Environmental Protection Agency (EPA), Office of Research and Development, National Risk Management Research Laboratory, Air Pollution and Prevention Divison (APPCD) , located in RTP, North Carolina has a requirement for multiple gas analyzers. The analyzers needed are as follows: one (1) heated total hydrocarbon analyzer with methane option; two (2) heated total hydrocarbon analyzers; two (2) heated nitrogen oxides analyzers and two (2) carbon Monoxide/carbon dioxide analyzers. This purchase request is for continuous emission gas analyzers to measure total hydrocarbons (THC), methane (CH4), carbon monoxide (CO), carbon dioxide (CO2) and nitrogen oxides (NO/NO2/NOx). The instruments will be incorporated into an existing continuous emissions monitoring (CEM) system to expand the research capabilities and improve the data quality of the cookstove research testing. The instrumentation requested will allow assembly of two complimentary CEM stations each having replicate instrumentation. One CEM station will continue to measure emissions from cook stoves under test and the second CEM station will be configured to continuously measure ambient background concentrations. As necessary, the second CEM station may be configured to monitor emissions for comparative analysis or serve as a backup source of emissions monitoring in case of component failure associated with the primary sampling station.
