Series 3800 Aerosol Time-of-Flight Mass Spectrometers with Aerodynamic Focusing Lens Technology

چکیده
Flight Mass Spectrometers (ATOFMS) in the 3800 series of instruments with built-in Aerodynamic Focusing Lens technology. Without a focusing lens, the ATOFMS samples particles from a variety of sources through a nozzle. Typically, particles from about 100 to 3000 nanometers are sampled with sharply decreasing efficiency for smaller sizes. To overcome this size bias, to sample smaller particles efficiently, and to achieve an overall higher analysis rate for all sizes, TSI developed two new ATOFMS instruments with built-in Aerodynamic Focusing Lens technology. Models 3800-030 and 3800-100 are mass spectrometers designed to effectively transmit partiDetermine size and chemical composition of individual

Characterization of an Aerodynamic Lens for Transmitting Particles Greater than 1 Micrometer in Diameter into the Aerodyne Aerosol Mass Spectrometer
We have designed and characterized a new inlet and aerodynamic lens for the Aerodyne aerosol mass spectrometer (AMS) that transmits particles between 80 nm and more than 3 μm in vacuum aerodynamic diameter. The design of the inlet and lens was optimized with computational fluid dynamics (CFD) modeling of particle trajectories. Major changes include a redesigned critical orifice holder and valve...
