Dispersion Technology Inc is a scientific instrument manufacturer located in Bedford Hills, New York. [1] 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]

Contents

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. [3]

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]
