The Naneum ‘SAC’ range of instruments includes portable size-selective devices which measure aerosol particle concentrations in the nano-particulate size range – that is down to one nanometre of diameter. They size resolve particulates in an air sample in up to 20 separate size bands.  Within each size band particulates are counted online to give an instant measure of the total number of particles and their size distribution. 

The Naneum ‘WRAS’ range of sampling instruments has a unique capability to collect ultra-fine particles in the nanoparticle and micrometer range sorted according to their size. Samples can then be analysed chemically and characterised physically using techniques such as atomic adsorption, mass spectroscopy and electron microscopy.

Naneum instruments have many advantages over competitor devices ranging from portability to low cost, and from accuracy to simple operation; these are described in the products section.

Naneum instruments have applications in:

• Industry (such as monitoring exposure where industrial processes give off particulates, or quality control of nanoparticle manufacturing processes)
• Environmental monitoring and occupational health (in an air sample containing particulates, their size and number are key parameters driving exposure). 
• Measuring the air quality in clean rooms and investigating sources of contamination
• General research in nano-science.

In 2005 the UK Government considered that one of its two main priorities for research were “The development of robust and reliable measurement and detection technologies for nanoparticles and nanotubes.  This work is of fundamental importance in determining and monitoring potential exposure routes both in the work place and the environment”. Naneum instruments provide the means to do just that…..
