PRODUCT DETAILS

The 1nm SMPS system combines TSI's historical strengths in particle classification and counting, with new technology that permits the measurement of particles as small as 1nm. The optimized Differential Mobility Analyzer 3086 further reduces diffusional losses of those smallest of particles. Between the DMA and a standard CPC, the NanoEnhancer Model 3757 uses diethylene glycol to pre-grow 1nm particles to enable detection by the CPC. The new Nano Enhancer design tightens the integration between CPC and Nano Enhancer and makes the setup and system use much easier.
Combining these components allow researchers to move particle research into exciting new territory. Key applications are:

Atmospheric Research - Monitor new particle formation and kinetics, cloud condensation, and close the gap between mass spectrometer and conventional particle size distribution measurements. Ideal for studies on sub-3 nm particles in highly polluted cities, particle sources and health effects studies.
Material Science - Monitor and characterize sub-3 nm particles with reliable, near real-time feedback. This system is ideal for aerosol-based engineered nanoparticle synthesis, nanoparticle functionalization, nanoscale analytical chemistry, control of reaction kinetics and catalyst synthesis.

The 1nm SMPS spectrometer is not just another detector that observes nucleation bursts from 1nm on; it is a full-blown particle spectrometer that shows which size distributions exist during these events, with an unmatched resolution.
The modularity of components makes it easy to customize the system to best fit your measurement needs: saving you time and money. If you already own one of the 3938-series SMPS systems configured with a 3750 CPC, you only need to add the 1nm-DMA and the Nano Enhancer. Your Classifier and Advanced Neutralizer will remain the same, and you will get a free update to the latest version of Aerosol Instrument Manager® software.
