High-Volume PM10 Sampler

A high-volume PM10 cyclone sampler is developed. This cyclone is a multi-inlet cyclone that can segregate particulate matter >10 micron size and facilitate to collect ≤ 10 micron size particles suspended in ambient air on filter size (8 × 10) inch. The cyclone is designed for sampling air with a high flow rate (1.13 m3/min, i.e. 40 CFM). Also, the design of this cyclone is made in such a way it can be retrofitted on the filter holder of a conventional high-volume total suspended particulate matter (TSPM) sampler to make it a high-volume PM10 sampler. The sampler's performance under all Indian weather conditions has been checked and found to be better than the existing sampler with several advantages.

Ambient PM10 mass, extensive chemical analyses, perfect sampler for source apportionment studies.

Simple design, No cutoff shift even at high particle mass loading and humidity conditions, consistent sampling flow even after 24 hours of sampling.
