#3 Real-Time CNT Monitor The NANODEVICE project at a glance The main goal of NANODEVICE is to develop innovative concepts and reliable methods for characterizing engineered nanoparticles (ENP) in workplace air with novel, portable and easy-to-use devices suitable for workplaces. visit www.nano-device.eu Instrument description Innovative Aspects: Real-time device capable of detecting very low concentrations of CNT against high concentrations of background ambient aerosols Physico-chemical pre-conditioner Measured physical metric: Number concentration. Using certain assumptions it is possible to calculate mass concentration of CNTs Type of nanoparticles: CNTs Intertial/diffussion separator Particle size range of operation: CNTs Ability to separate a source of ENP from the background? Yes Physical principle(s) of operation: CNT particles in the air are pre-selected using certain physical/chemical characteristics of CNT. Individual CNT objects are then counted using optical techniques. Pump and flow control system Optical selective counter Size, weight and power supply: Currently mains operation, could be battery operated Portable (5 kg weight) Size of prototype approximately 20 cm x 15 cm x 15 cm. Characteristics of workplace use: For all workplaces Data analysis and output Level of development: Near market Further opportunities: Proposed OELs for CNT are low so the device meets the requirements for monitoring exposures at these levels enabling the safe and sustainable exploitation of CNT Contact: Robert Muir Naneum Limited Canterbury Innovation Centre University Road Canterbury, Kent CT27FG, United Kingdom Phone: +44 (0)1227 81 1705 Fax: +44 (0)1227 81 1701 muir@naneum.com www.naneum.com
