Product Discontinued New Model ELPI+ now available
ELPI™ (Electrical Low Pressure Impactor) is an instrument to measure airborne particle size distribution and concentration in real-time. It operates in the size range of 7 nm – 10 µm, and can be applied to various different types of measurements where the requirements for the instrument include wide particle size range and fast response time. Because of its rapid response, the ELPI™ is an ideal measurement instrument for the analysis of unstable concentrations and size distributions, or the evolution of size distributions. Typical applications for the ELPI™ include combustion aerosol and engine exhaust studies, pharmaceutical inhaler development, air quality measurements and general aerosol research.
In ELPI™ the well-known impactor technology is combined with particle charging and electrical detection. The result is a robust instrument to measure particle size distribution in a wide size and concentration range, accurately and in real-time. The use of impactor technology also enables post-measurement chemical analysis of size classified particles. The ELPI™ can also be used to measure particle charge distribution in real-time, and make gravimetric impactor measurements.During the measurement, the ELPI™ instrument is completely controlled and data saved with easy-to-use ELPIVI software. Besides controlling the instrument operations, the ELPIVI enables monitoring of total concentration and particle size distribution of the sample in real-time. The software also enables operating of several ELPI™ units with one piece of software and sending the data or using the instrument over a network connection.
