Aerodynamic particle size spectrometer

Model: 3321

TSI in the United StatesThe 3321 Aerodynamic Particle Size Spectrometer (APS3321) is a high-performance, multi-purpose next-generation particle measurement instrument with a unique design that can simultaneously measure the following two properties:

Aerodynamic particle size: APS 3321 can measure the aerodynamic particle size of particles in real-time through precise time-of-flight (TOF) technology. Its particle size measurement range is 0.5-20 µ m. Due to the fact that aerodynamic particle size counting based on flight time is only related to particle shape. Thus avoiding refractive index and meter scattering instruments. In addition, the monotonic curve of time-of-flight particle size measurement ensures high resolution throughout the entire particle size measurement range.

Optical scattering intensity: measured through optical scattering techniques. The measured particle size of TSI APS 3321 in the United States can reach 0.37-20 µ m. Although the light scattering intensity is not always a reliable characterization parameter for particle size. But it is still a parameter of interest to people. APS 3321 can provide data on the aerodynamic particle size and optical scattering intensity of the same particle separately. And stored separately.

By measuring the aerodynamic particle size and optical scattering intensity of each particle through the same sensor, you can gain exciting new insights into the composition of aerosols. APS 3321 uses a continuous bimodal optical system with US patent * technology to detect the frequency of particle overlap events (multiple particles simultaneously passing through the detection area). And identify weak signals close to the detection limit. Therefore, the obtained detection results are solid, reliable, and high-quality data

APS 3321 has a beautiful and elegant appearance, as well as a simple and easy to operate front panel (including control knobs and built-in display screen). The control knob facilitates users to scan and view data on the display screen. Different functions of monitoring or controlling instruments. In addition, the instrument also has a volume flow controller controlled by microprocessor, atmospheric pressure correction, independent sheath gas sampling pump, and total sample gas sampling pump. These features ensure that APS 3321 can operate normally and maintain automatic calibration under various conditions. The Particle Instrument Management Software (AIM) is a sampling software based on a 32-bit WINDOWS program, which ensures that each 3321 has complete system and data control functions.
