Series 3936 Scanning Mobility Particle Sizer™ (SMPS) spectrometers measure particles from 0.0025 to 1.0 µm. They display data using up to 167 actual size channels (up to 64 channels per decade) for the highest resolution and accuracy available.
SMPS systems employ a continuous, fast-scanning technique. This was an industry first, and it eliminates gaps in particle-size-distribution data and allows measurements to be completed as few as 30 seconds. Additionally, SMPS systems are capable of measuring a very wide concentration range from 1 to 108 particles/cm3.
Thanks to the versatility afforded by the individual components, SMPS systems are suited for a wide range of applications. They feature the Series 3080 Electrostatic Classifier platform, which can be used with your choice of Differential Mobility Analyzer (DMA), and a large selection of Condensation Particle Counters (CPCs). This enables you to select a system that best fits your sizing requirements. These particle sizers provide additional flexibility by allowing you to adjust the sample flow rate (from 0.2 to 2.0 L/min), which effectively lets you select the particle size range of interest.
Computers for data collection must be purchased separately.
The Low-Flow Thermodenuder removes precursors and volatile particles from an aerosol sample for subsequent measurement of dry particle size.
The Nanometer Aerosol Sampler (NAS) allows you to sample charged particles, like those from the output of a Differential Mobility Analyzer (DMA), onto sample substrates for further analysis.
The TSI Rotating Disk Thermodiluter is highly regarded in the field of particle emission measurement, especially for sampling, diluting and conditioning exhaust from diesel and spark-ignition engines.
