The Dekati Classic ELPI (Electrical Low Pressure Impactor) enables measurement of real-time particle size distribution and concentration in the size range of 7 nm - 10 μm. With the ELPI, well-known impactor technology is combined with particle charging and electrical detection. The result is a robust instrument which measures 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 for real-time particle charge distribution and gravimetric impactor measurements.
