Laser Aerosol Spectrometer

TSI’s Laser Aerosol Spectrometer Model 3340 is a general purpose aerosol particle sizer which combines ultra-high sensitivity and superior resolution with ease-of-use. The Laser Aerosol Spcectrometer is a handy tool to have for monitoring your filters or your processes; measuring in a lab; or sampling on field campaigns.

TSI’s Laser Aerosol Spectrometer Model 3340 is a general purpose aerosol particle sizer which combines ultra-high sensitivity and superior resolution with ease-of-use. This 'turn on and measure' instrument allows users to easily measure a size range of 0.09 (90 nm) to 7.5 µm. Complete size distributions are measured in less than a second by simply powering up and sampling. Configurable size channels enable users to zero in on a specific size range or match the resolution of another instrument.

The Laser Aerosol Spcectrometer is a handy tool to have for monitoring your filters or your processes; measuring in a lab; or sampling on field campaigns. It's as useful as your primary aerosol tool, but the 3340 can also provide valuable supplemental information to aerosol measurements based on other sizing techniques (i.e. SMPS, APS, CPC, FMPS, etc.).

The 3340 Laser Aerosol Spectrometer is suitable for a wide range of applications. A few are highlighted below:

Filter Testing: The high resolution, wide concentration range, low end size detection limit and fast  measurement time make the 3340 ideally suited for filter testing applications.

•  Filter Efficiency Testing
•  Disk Drive Filter testing
•  Disk Drive Development and Research

Indoor Air Quality: As a stand alone instrument, the Laser Aerosol Spectrometer provides highly resolved particle size information over a wide concentration range. Pair the 3340 with a CPC, and you can measure the nanometer size fraction (<100 nm) easily and in real-time.

Atmospheric Research & Environmental Monitoring: The size range, measurement time, and lack of radioactive sources or working fluids make this a very useful instrument to fly in aircraft or to transfer from
environmental sampling point to environmental sampling point.

Inhalation Toxicology & Exposure Monitoring: Ease of use, fast measurement time and accuracy when measuring aerosols of a known composition make this a frequent application for the model 3340.
