equipment - Dekati Low Pressure Impactor (dlpi)
DLPI is a cascade low pressure impactor which classifies airborne particles into 13 size fractions. The size classification is made from 30 nm up to 10 μm with evenly distributed impactor stages. An additional back-up filter can be used to collect particles smaller than 30 nm. The impactor is available with a 10 and 30 l/min sample flow rate. The operating principle of the DLPI is based on inertial size classification and gravimetric or chemical analysis of the collected particles. The DLPI features low inter-stage walllosses, a small particle collection area 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 aerosol device testing.
