ELPI+™ (Electrical Low Pressure Impactor) is a new, improved version of the widely used and well characterized ELPI™ system. ELPI+™ enables measurement of real-time particle size distribution and concentration in the size range of 6nm - 10μm with 10Hz sampling rate. The ELPI+™ features include real-time stand-alone operation, wide sample concentration range, wide particle size range and robust structure for operation even in harsh conditions. The use of impactor technology enables post-measurement chemical analysis of size classified particles. In addition to gaining real-time particle size distribution data, the ELPI+™ can be used for real-time particle charge distribution and gravimetric impactor measurements. All these features enable the use of the ELPI+™ instrument in wide range of particle measurement applications including combustion aerosol and engine exhaust studies, pharmaceutical inhaler development, air quality monitoring and general aerosol research.
ELPI+™ features include:
- Wide particle size range; 6nm – 10μm
- 14 particle size fractions
- 10Hz sampling rate
- Possibility to collect size classified particles for chemical analysis
- Wide operational concentration range
- Independent stand-alone operation or control via laptop using ELPI+VI software
- Large 7” WVGA display with graphic user interface
- Analogue inputs and outputs
