Abstract
Emerging and continuing trends in basic and applied aerosol research in the past several years have emphasized the need for portable, robust, and lower-cost measurement devices that still maintain sufficient accuracy and repeatability for confidence in the results. Applications with growing interest include indoor and outdoor ambient monitoring, mobile measurements of dynamic processes, and occupational health and safety assessment. TSI has developed a Portable Water-based Condensation Particle Counter (PWCPC) that serves this growing market and application space. The device makes dynamic, high-quality measurements more accessible for a broader audience, and has evolved from TSI’s expertise in developing multiple generations of research-grade CPC technology.

This presentation will cover the underlying working principles and performance characteristics of the TSI OmniCount™ PWCPC including counting accuracy, detection efficiency and linearity, false count performance, time response, wick life, and influences of environmental factors on device performance. The presentation will conclude with examples of data from real-world usage to show the capabilities of the device and how it can help researchers meet their measurement goals and objectives.
