There are many tiny aerosols in the atmosphere that affect our lives, although we often do not realise or sense their existence. A complex mixture of solid and liquid particles from natural and anthropogenic sources, primary particles are continuously emitted into and secondary particles are formed in the atmosphere.
The atmospheric aerosol has a profound effect on our lives. It affects global climate, weather, visibility, and personal health. An extreme example is the London smog disaster in 1952, which caused thousands of deaths primarily due to pneumonia, bronchitis, tuberculosis, and heart failure.
Comprising complex mixtures of various organic and inorganic compounds, the growing population and industrial activities have led to a continuous increase in the emission of atmospheric aerosols and potential risk to health.
Advancements in aerosol measurements have been implemented in Ancon instruments and devices, providing an opportunity to characterise air quality and properties of atmospheric aerosols. Their portability and ease of use makes them ideal for many applications requiring detection of nano and micron measurements of airborne chemicals.
The Aero Select is a unique sampling system able to collect and quantify the entire aerosol size distribution to determine the concentration of contaminate particles in man-made applications against a background of naturally occurring aerosols from processes such as combustion.
Relevant Products for Atmospheric Aerosol Applications:
The Aero Select is a wide-range sampler and is unique in that it spans the entire aerosol range from 2nm up to 20μm. Particles are collected simultaneously using both inertial deposition and diffusion, and separated into 12 size channels.
A companion product for the Aero Select, the MR250 is used to determine mass-size distributions quickly, eliminating the need for laboratory gravimetrical analysis. The mass reader uses the light scattering characteristics of aerosol particles to quantify the masses of samples taken with the Aero Select in the size range of 250 to 35000nm.
