High-Volume PM2.5 Impactor Sampler

A high-volume PM_2.5 impactor sampler is developed. This impactor can segregate particulate matter >2.5 micron size and facilitate to collect ≤ 2.5 micron size particles suspended in ambient air on filter size (8 × 10) inch. The impactor is designed for sampling air with a high flow rate (1.13 m³/min, i.e. 40 CFM). Also, the design of this impactor is made such as a retrofit on the filter holder of conventional high-volume total suspended particulate matter (TSPM) sampler to make it high-volume PM_2.5 sampler.

Ambient air quality monitoring, PM2.5 mass concentration, extensive chemical analyses, perfect sampler for source apportionment studies

Indigenous development, first of its kind in India, impactor-based design with better and stable PM2.5 cutoff size, reliable high-volume sampling capabilities under Indian ambient conditions, perfect for source apportionment studies
