Engine Exhaust Particle Sizer (EEPS) 3090

SKU: 3090

Measure particle size from 5.6 to 560 nm at 10 Hz to visualize the dynamic behavior of particle emissions. Transient test cycles, the first few seconds of a cold start, and regeneration of a particle trap or diesel particulate filter (DPF): all of these require a particle sizer that can respond rapidly. The Engine Exhaust Particle Sizer (EEPS™) was designed for exactly these applications. The EEPS can be used with PC-based software, or integrated into a test cell via AK or serial commands.

Product Details

TSI's Engine Exhaust Particle Sizer (EEPS™) 3090 spectrometer uses an array of sensitive electrometers, combined with three proprietary data inversion matrices, to provide real-time particle size data in 32 size channels (16 channels per decade). 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. The EEPS spectrometer does not include any built-in sample dilution, giving the user maximum flexibility and independence with respect to sample conditioning. However, for measuring solid particles from engines, TSI now offers the Porous Tube Thermodiluter (PTT) 3098, a fully integrated sample conditioning solution for the EEPS spectrometer; the pair of them together is the Engine Exhaust Particle Measurement System (EEPMS) 3095.

The EEPS spectrometer operates at ambient pressure to prevent evaporation of volatile and semi-volatile particles; consumables or an external vacuum pump are not required. Providing size distributions and number concentrations (ranging down to 1,000 particles/cm3) ten times a second, the EEPS spectrometer has been proven to be a valuable tool for automotive emissions engineers and aerosol researchers.
