Sunset Laboratory Inc. was founded in 1984 by Bob Cary, a pioneer in the field of organic carbon and elemental carbon (OC-EC) aerosol analysis. The thermal-optical technique developed by Bob at the Oregon Graduate Center was adopted as the analytic method for OC-EC measurements by the National Institute for Occupational Safety and Health (known as NIOSH method 5040). In recognition of this achievement, Bob received the 1996 Alice Hamilton Award and the 2021 AS&T Outstanding Publication Award as co-author of the method. The sample sources Sunset Laboratory analyzed by this method are collected in various environments for multiple purposes. Sources range from ambient urban and rural areas to mining sites, work environments, national parklands, forest fire plumes, and sites of other unusual events. Our instruments have become the analytic equipment used for OC-EC in more than 40 countries and are ready for use with the NIOSH method 5040, IMPROVE, and EUSAAR2 protocols. Highly configurable operating parameters also allow for custom-designed analysis.
