ApplicationsNaneum instruments can be used for a number of applications. Atmospheric AerosolAtmospheric 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. Advancement in aerosol measurements implemented in Naneum instruments and devices provides an opportunity to characterise air quality and properties of atmospheric aerosols. Read More Combustion AerosolsStationary combustion sources such as those burning coal, fuel oil, biomass, and waste, are significant sources of combustion aerosols. Mobile sources from internal combustion (IC) engines burning gasoline and diesel are also a significant source of primary particles. Combustion sources can generate small particles ( <30nm) and close to the source such particles may be present in high concentrations. Depending on the concentration, particles can agglomerate to form larger particle sizes. Read More Occupational HealthHealth effects are known to depend on particle size and number as well as the chemical nature of the particles. The National Institute for Occupational Safety and Health (NIOSH) have launched a five year programme to investigate the impact of nano-particles on human health and the US EPA has allocated significant funds for developing regulations to control the release and presence of nano-particles in the air. Read More Environmental MonitoringThere 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 been on diesel emissions, but attention is turning to other potential sources such as power generation, incineration, nuclear power generation and aircraft emissions. The US EPA is becoming increasingly concerned about gasoline engine emissions. Data on exposure, and sources of nanoparticle sizes, number and composition would be the basis of developing standards and emissions regulations. Read More Clean RoomsThere 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 20n. In biological clean rooms viruses are typically in the nanoparticle size range and other biological agents such as enzymes, proteins etc. can be present in sizes below 100 nm. Read More Aerosol and NanotechnologyThe general R&D market with respect to nanotechnology is now large and growing quickly. It includes product development research across a very wide field of activities The USA National Science Foundation estimates the nano market will rise to US$1 trillion by 2015. Government investment in Nanotechnology now exceeds US$3 billion per annum. Read More |
