TSI - Model 3090 - Engine Exhaust Particle Size Spectrometer EEPS
From Particle Sizers
The EEPS uses an array of sensitive electrometers, combined with three proprietary data inversion matrices, to provide real-time particle size data in 32 size channels. The data inversion matrices allow the researcher to optimize size distribution accuracy for specific particle types (soot, default and compact), and matrices can be applied at the time of measurement or in a post-processing environment. It does not include any built-in sample dilution, giving the user maximum flexibility and independence with respect to sample conditioning. It operates at ambient pressure to prevent evaporation of volatile and semi-volatile particles. Providing size distributions and number concentrations down to 1000 #/cm³ ten times a second, it has been proven to be a valuable tool for automotive emissions engineers and aerosol researchers.
