Electrical Low Pressure Impactor

ELPI®+ enables measurement of real-time particle size distribution and concentration in the size range of 6 nm – 10 μm with 10 Hz 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. In addition to gaining real-time particle size distribution data, the ELPI®+ can be used for real-time particle charge distribution and for gravimetric impactor measurements. The use of impactor technology also enables post-measurement chemical analysis of size classified particles. 14 particle size fractions and 10 Hz sampling rate. Possibility to collect size classified particles for chemical analysis.
