Product Details

The SMPS TM Scanning Mobility Particle Size Spectrometer from TSI is widely used as a measurement standard for aerosol particle size distributions below 1 micron. The system is also used to make accurate nanoparticle size measurements of suspended particles in liquids. The National Institute of Standards and Technology (NIST) uses the TSI Differential Electrostatic Mobility Analyzer (DMA) to measure standard reference particle sizes of 60 nm and 100 nm. SMPS TM Scanning Mobility Spectrometer Particle Size Measurement is a prudent technique where the counting concentration is measured directly without making assumptions about the shape of the particle size distribution. The method does not depend on the refractive index of the particles or liquid and has a high degree of absolute particle size measurement accuracy and measurement repeatability.TSI's Model 3938 is the third generation of SMPS and has been trusted by researchers for 30 years.
