The paper develops a capture efficiency assessment system intended to speed up and simplify traditional capture-efficiency evaluation, using a static chamber-aerodynamic particle sizer (APS) combined with dust concentration sensors at multiple chamber positions to monitor particulate concentration uniformity and stability. The system is applied to evaluate a PM2.5 cyclone sampler across varying sampling flow rates using polydisperse particles, producing capture-efficiency curves rapidly—within about 1 minute—when flow rates are changed. A key limitation explicitly noted is that the work is presented as a preprint and had not been peer reviewed at the time of posting. The paper does not explicitly discuss endometriosis or adenomyosis; it was included in the corpus via a keyword match in the upstream search index.

Abstract

Abstract In response to the issues of time-consuming and cumbersome operations associated with traditional capture efficiency evaluation methods, a capture efficiency assessment system based on a static chamber-aerodynamic particle sizer (APS) has been developed for rapid dynamic visual evaluation of capture efficiency. The uniformity and stability of particulate matter concentration within the chamber were monitored through dust concentration sensors installed at multiple positions. The developed system was then applied to evaluate a PM2.5 cyclone sampler under varying sampling flow rates. Results demonstrate that the system enables rapid and accurate assessment of the sampler using polydisperse particles. When switching sampling flow rates, it generates capture efficiency curves within 1 minute, achieving dynamic visualization of the sampler's capture efficiency.
