The TPS100 nanoparticle sampler is the first fully self-contained, handheld thermophoretic sampling device on the market. This device collects airborne particles directly onto an electron microscope (EM) grid, which can be analyzed directly (no preparation required) using a high resolution EM to obtain detailed characterization of airborne nanoparticles.
Based on the principle of thermophoresis, or thermal precipitation, the TPS100 has an internal temperature gradient that drives particles to the EM grid, regardless of the sampler’s orientation. Projects to date using the sampler include:
- Placement in the International Space Station for air quality analysis
- Evaluation of cerium particles in diesel fuel emissions
- Investigation of siloxane in the atmosphere
- Characterization of secondary organic aerosols
- Evaluation of emissions from 3D printing
- Characterization of aerosols released from composite nanomaterials
- Assessment of the release of nanocellulose from a production process
- Characterization of combustion
- Study of the release of ultrafine metal particles from commercial products with small electric motors.
