DLPI (Dekati® Low Pressure Impactor)

Equipment Manager: Nakkyu Chae

DLPI (Dekati® Low Pressure Impactor) is a 13-stage cascade low pressure impactor to determine particle gravimetric mass size distribution. The size classification in DLPI is made from 30 nm up to 10 µm with evenly distributed impactor stages and can be extended down to 30 nm with an additional back-up filter. 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. Other DLPI characteristics include low inter-stage wall-losses(2 and robust yet easy-to-use operation. The rigid stainless steel construction of the DLPI makes it suitable for a wide variety of applications including power plant and vehicle emission measurements, engine blow-by measurements, air quality studies and pharmaceutical inhalation aerosol device testing.
