Dekati - Model DLPI+ -Low Pressure Cascade Impactor

The DLPI+ classifies and collects particles into 14 size fractions in the range of 16 nm – 10 μm. In each size fraction, the particles are collected on 25 mm collection substrates that are weighed before and after the measurement to obtain gravimetric size distribution of the particles. A chemical analysis of the size classified particles can also be performed. The DLPI+ impactor can be used in  various particle measurement applications and can the high temperature version of the DLPI+ can also be heated up to 180 °C for direct sampling of high temperature aerosols. Since the DLPI+ impactor has the same design as the impactor used in the Dekati^® ELPI^®+ (Electrical Low Pressure Impactor), it can easily be upgraded into a full ELPI^®+ system for real-time particle size distribution measurements.
