Scanning Mobility Particle Sizer Spectrometer 3938

SKU: 3938L88

For more than 30 years, the TSI SMPS spectrometers have helped gain new insights in aerosol research and assisted with calibrating reference material and other aerosol 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. Featuring a modular, component-based design, the 3rd generation model 3938 SMPS features very high size resolution, fast scanning (< 15 seconds per scan), and automatic component recognition. Easy to use, and providing the highest quality data available, the TSI SMPS is the researcher's choice for nanoparticle size distribution measurements.

Product Details

The SMPS 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 64 channels per decade, resulting in up to 109 channels in total.

The SMPS Model 3938 is component-based, allowing users to customize their SMPS to match their experimental needs. Users may choose among three DMAs, seven CPCs, and two different neutralization techniques, enabling measurement from 1 nm - 1 um. 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.
