Founded in 1991 around Prof. Daryl Williams’ invention of Dynamic Vapor Sorption, Surface Measurement Systems designs scientific instruments and provides contract services for characterizing how solid materials interact with moisture, vapors and gases. The company delivered its first DVS analyzer to Pfizer in 1992 and later pioneered commercial Inverse Gas Chromatography, building a global business serving materials researchers from pharmaceuticals to porous materials and carbon capture. Its instruments and laboratory services are supported by ISO 9001:2015 and ISO 45001:2018 certifications.
