Recently, a great deal of attention has been focused on the sampling of toxic substances in the form of organic vapors and particulate. Such decrees require the closest monitoring of all the substances present in the external Environmental and particularly harmful to human beings, such as fine particles (PM10 and PM2,5), micropollutants (IPA, PCDD, PCDF), ozone and relevant precursors (VOC and formaldehyde), metals.
Gravimetric dust monitoring is the most used technique for monitoring dust particles in ambient air and it involves sampling a known volume of ambient air through a filter. The filters are weighed before and after exposure to determine the mass of particles. The collected dust sample is expressed as the mass of dust (mg) per cubic meter (m3) of air. Continuous measurement of particulate emission concentrations which, for a defined range of application conditions, can be calibrated against isokinetic gravimetric test samples (Standard Reference Method). Dust Samplers of different configurations play a pivotal role in this measurement technique. AlfaTech Services provides devices used to monitor air and workplace parameters, Environmental and chimney emission control. Our constant pursuit is to provide optimal solutions to the Indian research fraternity for making more and more reliable sampling.
