Description
DESCRIPTION (provided by applicant): A Personal Nanoparticle Counter This proposal addresses the need for a rugged, wearable instrument for the precise, real-time monitoring of airborne number concentrations for fine, ultrafine and nanometer-sized particles. Proposed is a new type of laminar-flow water condensation method that detects and counts particles as small as 5 nm in a tippable device. We aim to demonstrate the feasibility of this technology for a portable and potentially wearable device, to measurenanometer and ultrafine particle concentrations with 1-s time resolution. Additionally, we will demonstrate its suitability for long term monitoring when power source is available. Specific aims are: 1) to verify the feasibility of a miniature, water-based condensation particle counter capable of: detecting at least 50% of particles with a diameter of 6 nm; detecting at least 95% of those particles with diameters above 10 nm; measuring particle concentrations from 103 - 106 cm-3; providing 1-sec
