Aerosol and Nanotechnology

Research and Development There is a great deal of concern about the health effects of nanoparticles released into the environment unintentionally and effective instrumentation is an essential prerequisite for research into all aspects of nanotechnology. Since the effects of nanoparticles are determined by their size and number these are the key basic attributes which must

Clean Rooms

There are thousands of clean rooms in the micro-electronics, pharmaceutical, medical, laser, and fibre optics industries. Standards of air quality and monitoring and control vary. Typically, control is at the micron level. However, there is a shift towards sub-micron measurement and monitoring. For example, Nanoelectronics demands measurements at 40nm and even 20nm. In biological clean

Environmental Monitoring

There is a great deal of concern about the health effects of nanoparticles emitted unintentionally into the air, largely from combustion processes. For example, the 500% increase in respiratory illness and allergies in the UK has been associated in part with particles emitted by diesels and other combustion processes. Focus has beenĀ on diesel emissions (predominantly

Occupational Health

All heavy industries involving processes emitting fumes have potential problems with the emission of nano-particles. This includes industries such as smelting, firing, glass manufacture, welding, soldering, nuclear power generation and incineration. There is also concern amongst consumer companies that enzymes in washing powders, powder coatings and fibres used in disposable nappies and other products could

Combustion Aerosols

Stationary combustion sources such as those burning coal, fuel oil, biomass, and waste are significant sources of combustion aerosols. Mobile sources from internal combustion engines burning gasoline and diesel are also a significant source of primary particles. Combustion sources can generate small particles under 30nm and close to the source such particles may be present

Atmospheric Aerosol

Atmospheric aerosols comprise complex mixtures of various organic and inorganic compounds. The growing population and industrial activities have led to a continuous increase in the emission of aerosols. 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
