This is a Request for Information (RFI) only by the Naval Surface Warfare Center, Dahlgren Division (NSWCDD). NSWCDD is seeking information on existing, prototype, developmental and/or research configurations for an instrument to measure the particle mass concentration of varios polydisperse aerosol compositions inside a sealed chamber. The aerosol chamber has an approximate experimental volume of 0.5 cubic meters. There are multiple ports where instrumentation can be mounted to interrogate the internal volume. Known aerosols, consisting of either solid or liquid particles, are generated and suspended inside the chamber. The aerosol's particle mass and number concentration inside the chamber must be measured accurately to understand the chamber conditions. An accurate isokinetic measurement consists of reporting particle concentration over the entire particle diameter distribution of an aerosol. Solutions are sought to determine the existence of any instrumentat  ion that meets the requirements outlined in the "Parameters of Interest".

A Distribution D supplemental Parameters of Interest sheet is available, and all interested parties are encouraged to request a copy by email to the following address: [email protected]. In order to recieve this additional information for RFI, the company MUST include:

Company Name and Address

Primary Point of Contact (to include name and phone number)

Company NAICS Code

Company Cage Code

Responses to this RFI should include as much detailed information as possible to include technical system overview, system specification sheet, and calibration information.

NSWCDD requests offeror's responses NO LATER THAN 12:00PM EST 31 August, 2021; early submissions are find and encouraged. All communications must be coordinated through the Contract Specialist via e-mail at [email protected] or by phone 540-653-8237.
