In new air quality standard notified by Govt. of India where measurement of PM10 and PM2.5 dust is required with other pollutants to decide status of air pollution. So far samplers developed in India do not have provision for simultaneous sampling of PM10 and PM2.5 dust. Thus two samplers need to be operated simultaneously to know concentration of these pollutants in ambient air. This results measurement of these parameters expensive and difficult as significant efforts are required in transport of two samplers and their operation in field.
