Collecting high quality particle samples for laboratory analysis is a fundamental element of many aerosol research programs.

The fully-integrated SPOT SAMPLER™ instruments are designed for efficient, concentrated collection of nanometer to micrometer-sized aerosol particles.


Better samples for better results

The enabling technology is a moderated condensational growth that enlarges particles into water droplets without temperature extremes or steam. Once grown, particles that were as small as a few nanometers are easily captured by gentle impaction or impingement. Collection may be either wet or dry. Samples are ‘ready to analyze’ without user extraction or manipulation. This approach excels at collecting challenging materials such as nanoparticles, bioaerosols, and semi-volatile particles where other collection methods fail.

Condensation particle counting measures the number concentration of ultrafine aerosol particles using this same enabling technology. Rather than collecting a particle sample, the individual droplets are counted with a laser sensor.
