Scanning electric mobility particle size spectrometer

Model: 3938

TSI3938, the SMPS TM scanning electron mobility particle size spectrometer launched by TSI, is widely used as a measurement standard for measuring the particle size distribution of aerosols below 1 micron. This system is also applied to accurately measure the nanoparticle size of liquid suspended particles. The National Institute of Standards and Technology (NIST) in the United States measured the standard reference particle sizes of 60nm and 100nm using a TSI differential electrostatic mobility analyzer (DMA). The SMPS TM scanning electron mobility particle size spectrometer is a cautious technique for particle size measurement, in which the counting concentration is directly measured without assuming the shape of the particle size distribution. This method does not rely on the refractive index of particles or liquids and has high absolute particle size measurement accuracy and measurement repeatability. The third generation 3938 SMPS adopts a modular, component-based design, which not only has a very high particle size resolution, but also has fast scanning (less than 15 seconds per scan) and automatic component recognition function. TSI SMPS is easy to use and can provide researchers with the highest quality data, making it the best choice for measuring nanoparticle size distribution. TSI's 3938 instrument is the third generation product of SMPS and has been trusted by researchers for 30 years.
