Sources Sought Notice for unipolar diffusion aerosol charger

Description: NIST issued this active sources-sought notice, rather than a grant opportunity, to conduct market research for a commercial Unipolar Diffusion Aerosol Charger (UDAC) supporting Chemical Sciences Division Grand Challenge Project 1.04. The equipment must operate at volumetric flows ≤ 1.5 L min-1 and place a unipolar positive charge on aerosol, supporting aerosol research and calibration of condensation particle counters. Respondents must identify compliant products, manufacturer and model specifications, customization limits, manufacturing details, services, pricing, contract availability, customer references, and related capabilities by email without proprietary information.
