PM2.5 Sampler

Indigenous sampler to handle high-volume of air and with better cutoff size of PM2.5 particles. A high volume PM2.5 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 imapactor 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 highvolume total suspended particulate matter (TSPM) sampler to make it high-volume PM2.5 sampler

• PM2.5 Sampler can  be used to check quality of air in a given area.
• Sampler for air monitoring (as per NAAQS)

• Indigenous, first in India               
• Impactor based sampler                      
• Better cutoff size of PM2.5 particles.
