The Environmental Protection Agency (EPA) is seeking information for the procurement of a high time resolution and wide particle size distribution analyzer, which includes installation and configuration services. The agency aims to acquire one analyzer that meets specific technical specifications, including the ability to measure particulate matter across a wide size range and provide detailed data output compatible with existing EPA systems. This equipment is crucial for enhancing the EPA's capabilities in environmental monitoring and analysis. Interested parties should submit their responses to the Request for Information (RFI) by December 23, 2024, via email to OARNVFELSACO@epa.gov, as the EPA will not accept telephone inquiries or cover any costs associated with responses.
