High Temperature ELPI+ Particle Measurement System

The Dekati® High Temperature ELPI®+ (Electrical Low Pressure Impactor, HT-ELPI®+) is a unique version of the Dekati® ELPI®+ that enables real-time measurement of particle size distribution from 6 nm up to 10 μm with 10 Hz sampling rate. The High Temperature ELPI®+ allows direct measurement of up to 180 °C aerosol samples without the need to cool the sample, which makes the HT-ELPI®+ a one of a kind tool to characterize high temperature aerosols.

The operating principle of the High Temperature ELPI®+ is the same as that of the ELPI®+. In the High Temperature ELPI®+, the impactor and charger unit is separated from the ELPI®+main unit and placed inside a heating element. The heating element can be heated up to 180 °C allowing direct sampling of hot aerosols without the risk of condensation or sample transformations.
