FMPS Spectrometer Provides Real-Time Measurements of Rapidly Changing Aerosols

The Model 3091 Fast Mobility Particle Sizer (FMPS) spectrometer measures particles in the range of 5.6 nm to 560 nm, offering a total of 32 channels of resolution (16 channels per decade). Multiple, low-noise electrometers are used for particle detection. This produces particle-size-distribution measurements with one-second resolution and provides the ability to visualize particle events and changes in particle size distribution in real time. The instrument uses a high flow rate (10 L/min), minimizing diffusion losses of ultrafine and nanoparticles. It also operates at ambient pressure to prevent evaporation of volatile particles. It requires no consumables and is easy to transport, set up and operate. The instrument can be configured to measure single or multiple runs continuously for up to 12 hrs. A large, color VGA display and built-in control knob provide easy access to instrument features, set-up menus and data displays.
