Many workers in industrial settings are exposed to hazardous airborne particles. Potential health risks associated with this are quantified using particle sampling techniques such as the electrostatic precipitation (ESP), aerodynamic impact, gravitational settling, and vapor deposition. Although there has been some success with this technology, there are application limits: sampling efficiency drops significantly in the particle range of 100nm‐200nm. Currently, a portable particle sampling device capable of accurately collecting particles ranging from 1nm‐200nm is unavailable. Thermophoretic precipitation has the capacity to fulfill the demand for this sampling range. Our goal is to create a prototype which uses a temperature gradient across an air flow to collect nano‐particles.
