SBIR-STTR Award

A background study will be performed on the state-of-the-art specific materials and ion production techniques that can be added to IMS systems to improve sensitivity and specificity. Ion-molecule chemistry and signal processing algorithms that will allow interference rejection will be included. documented using test particles of known size characteristics and by measuring size characteristics of the sorted particles. Design information for the Phase II prototype will be developed using a parametric test sequence.

Benefits:
This project will delineate ion-chemistries and signal processing algorithms that will improve IMS detection of: a. Military chemical warfare substances b. Illegal drugs (cocaine, heroin, etc. and their precursors)

Keywords:
classification inertia particles size shape electrostatics charging Particle fibers flakes aerodynamic electrostatic separation

The proposed Phase II project will develop a concept for sorting powders by shape and size characteristics into a prototype for a production scale machine for several defense and industrial uses. The concept based on a combined aerodynamic and electrostatic separation of fibers and flakes from regular sized particles was shown to be feasible in a Phase I program.
