AEROSOL RESEARCH

TSI offers two Aerosol Time-of-Flight Mass Spectrometers (ATOFMS) for single particle size and chemical composition analysis. Series 3800 instruments include Aerodynamic Focusing Lens technology for a higher sampling efficiency and analysis rate. Models 3800-030 and 3800-100 transmit particles in the range from 30to 300 nm and 100 to 3000 nm, respectively.

The ATOFMS uses an aerodynamic sizing technique to size individual particles in real time. Then, it desorbs and ionizes some particles for chemical analysis in a bipolar, time-of-flight mass spectrometer. With MS-Control software, version 5.1 and 1GB of memory. It is capable of saving positive and negative mass spectra at a rate of up to 19 particles per second.

Because it identifies specific chemical compounds that make up each particle, the ATOFMS offers new insights into the dynamic chemistry of an aerosol sample. Already a revolutionary instrument in the field of analytical chemistry, the Model 3800 has great potential in application areas such as atmospheric science,biological detection, pharmaceutical manufacturing, and engine research.

Series 3800 Aerosol Time-of-Flight Mass Spectrometers were developed under license from the University of California, Riverside, United States Patent Numbers 5,681,752 and 5,998,215. Aerodynamic Focusing Lens technology is offered under license from the University of Minnesota, United States Patent Number 5,270,542.
