Fast Mobility Particle Sizer Spectrometer 3091

Request A Quote Accessories


The Fast Mobility Particle Sizer (FMPS™) 3091 spectrometer measures particles in the range from 5.6 to 560 nm with 1 Hz time resolution. This allows users to gather full size distributions of quickly-changing aerosols. This combination of two-decade size distribution and 1 Hz time resolution makes the FMPS a very valuable tool for monitoring particle exposures in rapidly changing environments, such as street canyons, airports, or mines. The FMPS 3091 is also valuable for characterizing emissions from rapidly changing sources, such as incineration, cigarettes, or printers.

Product Details

The FMPS 3091 offers a total of 32 channels of resolution (16 channels per decade). It uses an electrical mobility measurement technique similar to that used in our SMPS. However, instead of a CPC, the FMPS spectrometer uses multiple, low-noise electrometers for particle detection. This enables particle-size-distribution measurements in real time, providing the unique ability to visualize particle events and dynamic changes in particle size distribution.

The FMPS spectrometer operates at a high flow rate (10 L/min) to minimize diffusion losses of ultrafine and nanoparticles. It operates at ambient pressure to prevent evaporation of volatile particles, and it requires no consumables.

The FMPS is easy to transport, set up, and operate. Equipment be configured to measure single or multiple runs continuously for up to 12 hours in length. Its large, color VGA display and built-in control knob provide easy access to instrument features, set-up menus, and data displays.
