DMS500 enables real-time analysis of particle size and distribution. The analyser is mobile and connects to a sampling point via a sampling line to provide continuous online sample monitoring and analysis. It can be used for the analysis of soot or fly ash particulates in exhaust gases of the PACT 250kWth PF Air-Oxyfuel Plant or the PACT 330kWth CHP Gas Turbine, or to analyse aerosol formation on the PACT PCC Plant. The instrument uses electrical mobility measurements of particles with sensitive electrometer detectors enabling the generation of particle size, number and mass spectra in real time. The instrument has the fastest time response available and the widest available size range: from 5 ‒ 1000 nm well as the highest Sensitivity in Class.
