Water Condensation Particle Counting (WCPC)
Our company’s patented technology has led to a family of
instruments for measuring the number concentration of ultrafine and
nanometer-sized airborne particles.
Nanometer-sized particles are enlarged through water condensation in a
thermally diffusive flow to form micrometer sized droplets that can be
counted optically. Particles as small as 3 nm (0.003
can be detected.
Several models are available:
