DEKATI ELPI™ Electrical Low Pressure Impactor For more information, please contact: sales@dekati.fi Acknowledgements This instrument originated through work carried out at the Aerosol Research Group at Tampere University of Tech-nology, Tampere, Finland. The ELPI low pressure impactor was designed in co-operation with the Finnish Meteorolog- The Electrical Low Pressure Impactor (ELPI™) The ELPI (model 972E, Dekati Ltd., Tampere, Finland) classifies aerosols according to their aerodynamic diameter, D p , and collects real-time particle size measurements in the size range of 7 nm-10 µm. Dekati® Solutions Engine emissions Particle emissions from engines vary a lot depending on the type of engine and fuel used. Additional factors including engine load, ECU operation and environmental conditions also have an effect on the emissions. Particle emissions are commonly reduced using different after-treatment devices Particle Size Distributions of Particulate Emissions from the Ferroalloy Industry Evaluated by Electrical Low Pressure Impactor (ELPI) (ELPI, Dekati Ltd., Tampere, Finland) is the detection and quantification of particles as small as 7 nm. The ELPI also enables real-time assessment of the scielutions.com lizers. The Dekati® ELPI™ (Electrical Low Pressure Impactor, Dekati Ltd.) has been widely used to determine the net charge size distribution of inhalation aerosols. However, where the ELPI™ method gives the net charge of the particles, the new Dekati ® Bipolar Charge Analyzer (Dekati BOLAR™) is the and Dekati can offer aluminium and polycarbonate foils for this purpose. Other DLPI+ accessories include vacuum pumps, spare impactor collection plates and sampling inlets and lines for various applications. The DLPI+ design is the same as in the impactor used in the ELPI®+ (Electrical Low Pressure Impactor) enabling an easy upgrade from DLPI+ manual. The combination of ELPI TM and FPS enables fast and efficient studies of sample Effect of the Dekati ® Thermodenuder on particle size distribution measured with ELPI TM. In the Dekati Measurements of Diesel Particle Size Distributions with an Electrical Low Pressure Impactor The Dekati® High Temperature ELPI+­™ (HT-ELPI+™) is a new 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. Losses inside Dekati® diluter The particle losses of the Dekati® diluter have been determined with various flow rates using Electrical Low Pressure Impactor (ELPITM). For particles smaller than 1?m the losses proved to be negligible in all tests. For particles in the size range of 1-5 ?m, in the worst case, the losses were less than 10%.
