Handix Scientific has an active instrument research and development program, and we are working on a number of new measurement technologies to improve atmospheric research capabilities. Please contact us if you are interested in learning more about these technologies, or are interested in partnering with us to develop and/or commercialize technology you have developed in your lab!

The US Department of Energy has supported an SBIR Phase I project to develop a small static thermal gradient (STG) diffusion chamber for measuring cloud condensation nuclei. The instrument consists of a small cloud drop formation chamber, laser, and imaging system, which detects activated drops. Handix Scientific is collaborating with Donald Huffman, who co-developed the first commercial STG chamber in the 1990s, and his son, Alex Huffman, a professor at the University of Denver specializing in aerosol research.

Airborne INP Counter

We are collaborating with the highly experienced research team at Colorado State University to develop an airborne version of our Continuous Flow Diffusion Chamber for measurement of ice nucleaing particles. The work has been supported by a NASA Phase I SBIR. Our initial development efforts focused on replacing the measurement chamber of the ground-based CFDC with an all-aluminum construction to eliminate labor-intensive and difficult chemical treatment and cleaning processes required by the copper material used in the original instrument.

Microfluidic INP counter

We were also supported by the US Department of Energy to develop a microfluidic-based ice nucleating particle counter, in collaboration with Prof. Andrew Metcalf of Clemson University. This project uses microfludic technology to measure a flowing stream of liquid samples containing INP. The eventual goal is to produce a compact instrument capable of operating on unmanned aerial platforms, including UAS and potentially balloons.

The Office of Naval Research is supporting a development effort to modify our existing open-path cavity ringdown (OP-CRD) technology for use in measuring atmospheric light extinction at wavelengths relevant to directed energy applications.
