Dispersion Technology Inc is a scientific instrument manufacturer located in Bedford Hills, New York. It was founded in 1996 by Philip Goetz (former chairman, retired in 2010) and Dr. Andrei Dukhin (current CEO).[3] The company develops and sells analytical instruments intended for characterizing concentrated dispersions and emulsions, complying with the International Standards for acoustic particle sizing ISO 20998 [4] [5] and electroacoustic zeta potential measurement ISO 13099.[6]

Dispersion Technology manufactures a family of ultrasound-based instruments for measuring particle size, zeta potential, high frequency rheology, and solid content in concentrated systems without diluting them.[7]

Founders Dukhin and Goetz have written two books published by Elsevier describing the details of these methods, underlying theories, and applications of the instruments manufactured by Dispersion Technology.[8]

Co-Founder Dr. Andrei Dukhin and his father Dr. Stanislav Dukhin were the subject of a 2009 feature in the American Chemical Society documenting their research done in the former Soviet Union; their contributions to the fields of electrokinetics, colloid science, DLVO theory, etc.; and their immigration to the United States as a part of the Soviet Scientists Immigration Act of 1992.

Dispersion Technology maintains seven patents in the United States,[9] [10] [11] [12] [13] [14] and has representation in Japan,[15] Russia,[16] Europe,[17] Brazil,[18] South Korea,[19] China,[17] and Canada.[20]
