General Scanning Mobility Particle Sizer (SMPS) 3938

Choose your configuration of the global standard in aerosol size measurement. For more than 30 years, the TSI Scanning Mobility Particle Sizer (SMPS™) spectrometers have helped gain new insights in aerosol research and assisted with calibrating other instrumentation. The US National Institute of Standards and Technology (NIST) and many other reference laboratories worldwide use the TSI SMPS™ for submicrometer particle size distribution measurements. The TSI SMPS™ is the researcher’s choice for nanoparticle size distribution measurements.

Product Details

The Scanning Mobility Particle Sizer (SMPS™) spectrometer is a nanoparticle sizer capable of measuring the size distribution of airborne submicron particles with accuracy and precision. It combines electrical mobility sizing with single-particle counting to deliver nanoparticle concentrations in discrete size channels. The size resolution capability of the SMPS™ is as high as 128 channels per decade, resulting in up to 384 channels in total.

The SMPS™ 3938 is component-based, allowing users to customize their SMPS to match their experimental needs. Users may choose among four Differential Mobilty Analyzers (DMAs), six Condensation Particle Counters (CPCs), and two different neutralization techniques, enabling measurement in the range from 1 nm up to 1 µm. When an SMPS is coupled with an Optical Particle Sizer (OPS) or Aerodynamic Particle Sizer (APS), the continuous measurement range can be extended up to 10 µm or 20 µm, respectively.
