TSI's Scanning Mobility Particle Sizer Spectrometer 3936 spectrometer is a high resolution nanoparticle sizer that has long been hailed as the researcher's choice for nanoparticle size characterization for nano applications including nano research and development.
TSI's SMPS™ Spectrometer is widely used as the standard method to measure airborne particle size distributions. These particle sizers are also routinely used to make accurate nanoparticle size measurements of particles suspended in liquids. The National Institute of Standards and Technology (NIST) uses a TSI DMA to size 60 nm and 100 nm standard reference materials suspended in liquid (polystyrene latex spheres or PSL.
SMPS™ spectrometer sizing is a discreet technique in which number concentrations are measured directly without assuming the shape of the particle size distribution. The method is independent of the refractive index of the particle or fluid, and has a high degree of absolute sizing accuracy and measurement repeatability. Trusted by researchers, the TSI Scanning Mobility Particle Sizer™ Spectrometer (SMPS) has provided high quality data for over 30 years.
