{"id":730,"count":2,"description":"Dilution system to remove volatile particles and to dilute highly concentrated aerosols for PMPD applications\r\n---------\r\nThe PMPD dilution system is used for emission measurements of vehicles and jet engines.\r\n---------\r\nThe PMPD system is a dilution system according to the ejector principle that was especially developed for the PMP application or the PMP measurement chain.\r\n---------\r\nThe Particle Measurement Programme or PMP is a programme for advancing the particle measurement technique for particulate vehicle exhaust gases.\r\n---------\r\nThe PMPD consists of a vaporisation line heated to 200\u00b0C, a dilution line also heated to 200\u00b0C, the thermodiluter to remove volatile particles, followed by a second unheated dilution step. Each dilution step has a dilution factor of 1:10, which corresponds to a total dilution factor of 1:100.\r\n---------\r\nThe efficiency of removing volatile particles was determined at METAS with 30 nm sized tetracontane (C40H82) droplets in accordance with \"VPR Calibration Procedure AEA \/ ED47382 \/ Issue 5\" (Volatile Particle Removal Efficiency) and is 0.99967.
