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).{{cite journal|title= Electrokinetics: it's in their genes|journal=Analytical Chemistry |volume=81 |issue=11 |pages=4166–4168 |doi=10.1021/ac9006683 |pmid=19408938 |year = 2009|last1 = Mukhopadhyay|first1 = Rajendrani|doi-access=free }} 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 [http://www.iso.org/iso/iso_catalogue/catalogue_tc/catalogue_detail.htm?csnumber=39869 ISO 20998-1:2006 Measurement and characterization of particles by acoustic methods] -- Part 1: Concepts and procedures in ultrasonic attenuation spectroscopy[http://www.iso.org/iso/home/store/catalogue_tc/catalogue_detail.htm?csnumber=43468 ISO 20998-1:2013 Measurement and characterization of particles by acoustic methods] -- Part 2: Guidelines for linear theory and electroacoustic zeta potential measurement ISO 13099.[http://www.iso.org/iso/catalogue_detail.htm?csnumber=52807 ISO 13099-1:2012 Colloidal systems – Methods for zeta-potential determination] – Part 1: Electroacoustic and electrokinetic phenomena
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.{{cite web|url=http://www.dispersion.com |title=Dispersion Technology Homepage |publisher=Dispersion.com |date=2013-06-01 |accessdate=2018-02-07}}
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.[http://www.elsevier.com/books/characterization-of-liquids-nano-and-microparticulates-and-porous-bodies-using-ultrasound/dukhin/978-0-444-51164-5 Characterization of Liquids, Nano- and Microparticulates, and Porous Bodies using Ultrasound, ELSEVIER, 2010, 2nd Edition], Retrieved: 8 October 2013
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.
