Cedenna acquires equipment to measure nanoparticles in the air

May 7, 2020

Since this year, the Cedenna Center for the Development of Nanoscience and Nanotechnology has had a Mini WRAS (Wide Range Aerosol Spectrometer) capable of capturing particulate matter from the air, quantifying it and distributing it by size from 35 micrometers to dimensions as small as 10 nanometers, range that includes PM10, PM2.5 and PM1 particulate matter.
The Mini WRAS is a wide range portable aerosol spectrometer, a specialized machine for the measurement of particles in the air, and is part of the Cedenna Nanosecurity Laboratory.
The equipment allows the monitoring of air quality in buildings, offices, homes, gyms, vehicles, air cabins, buses, train cars, etc. according to the UNE-EN 481: 1995 standard for measuring work environments, a standard that specifies the possible scope of material aspirated by people, classifying it as inhalable, thoracic and breathable, depending on the size of the particulate material.
Thanks to its portability, it can measure nearby and identify nanoparticle emission sources and requires only a few minutes to detect and quantify.
The equipment is operated by the Nanosecurity Unit of the Cedenna research center, led by Dr. Mauricio Escudey.

The Cedenna Center for the Development of Nanoscience and Nanotechnology is a multidisciplinary and inter-university research center, installed at the University of Santiago and with specialists dedicated to the study and promotion of materials science at the nanometric scale and its applications
