TSI’s P-Trak® Ultrafine Particle Counter offers a new tool for industrial hygiene and exposure monitoring investigations.  Using Condensation Particle Counting (CPC) technology, this portable instrument detects and counts ultrafine and nanoparticles. 

Ultrafine particles are defined as having a diameter less than 0.1 um (or 100 nm).  Engineered nanoparticles (nanomaterials) are a subset of ultrafine particles with dimensions from 1-100nm.  Particles this small are capable of depositing in all areas of the lungs and are too small to be measured by traditional mass-based measurements.  Man-made sources of ultrafine particles include vehicle emissions, welding and combustion by-products, chemical reactions, and engineered nanoparticles.

The P-Trak can be used to assess workplace levels of ultrafine and nanoparticles to establish a baseline or identify areas of high ultrafine particle generation.  The P-Trak is easy to use, provides real-time measurement, and data logs information for follow up report generation.
