      • Sampling – How are you going to get your sample to your instruments with minimal particle losses? Do you need to worry about how ambient humidity variations will affect your sampling efficiency? With our in-house aerosol wind tunnel, cloud chamber and years of inlet design experience we can answer your questions and solve your sampling problems. Whether you are trying to develop an isokinetic inlet for a moving platform, a new method for distributing sample flows to multiple instruments, or a system for measuring ambient cloud droplets – contact us and we’ll propose the most cost-effective solution possible to satisfy your needs.

          • Pumped Counterflow Virtual Impactor (PCVI)
          • UAV inlet
      • Particle Sizing and Counting – If your measurement needs include sizing and counting aerosol, our Scanning Electrical Mobility Sizer, Humidified Tandem Differential Mobility Analyzer and Mixing Condensation Particle Counter have logged thousands of continuous ambient sampling hours at coastal sites, mountain sites, the South Pole, on ships at sea, and even on-board aircraft at 40,000 ft. We pay attention to the needs of real-world field sampling applications so you don’t have to worry about your instrument reliability. With data post-processing tools written in easy-to-use IGOR(™) software procedures, we make it easy to mine your data and produce publication-ready plots.

      • Chemistry and Black Carbon – Particle chemistry is complex, so is black carbon. Do you need to sample major water soluble species? Looking to better understand local sources of black versus ‘brown’ carbon? Interested in water soluble organics? Take some of the complexity out of these complex measurements by employing our Particle into Liquid Sampler (PILS) for applications where you need to know the ambient concentration of water soluble species like sulfate, nitrate and ammonium or our Tricolor Absorption Photometer when you want a simple-to-use measurement of black carbon.

Description

What if rain patterns change so much due to climate change that some people do not get enough water to grow their food? It may be possible to seed clouds with ice nuclei or other aerosol to induce rain. Our tools are used to determine which particles act as nuclei in real clouds, and to measure their key properties.
