Brookhaven Instruments
Encyclopedia
Brookhaven Instruments Corporation is a Nova Instruments company. Established in the late 1960s, Brookhaven Instruments pioneered modern techniques in characterizing nanoparticles, proteins, and polymers using light scattering
techniques such as dynamic, static, electrophoretic, and phase analysis for: particle size, zeta potential
, molecular mass
and absolute molar mass
analysis.
Product designs started when their founders were postdoctoral students in the late 1960s. Today, Brookhaven Instruments uses a variety of techniques including static, dynamic, electrophoretic, phase analysis light scattering and specialized centrifuge
technology to become one of the major players in the light scattering
instrumentation market.

understand how the properties of engineering materials are determined by their atomic structure. Using equipment supplied by Brookhaven Instruments Corporation in New York State, provided the key to solving fundamental problems in condensed matter physics, and lead to revolutionary new "designer" materials for the manufacturing industry.
They flew their apparatus, called PHaSE (Physics of Hard Spheres Experiment), into space in April 1997. It was one of a number of projects participating in NASA's Microgravity Science Laboratory-1 mission, aboard the Columbia. The long-duration microgravity environment provided by the shuttle made it an ideal platform for the study.
At the heart of the PHaSE investigations were two Brookhaven BI-9000AT Digital Correlators which interpreted the data from the light scattering apparatus, sampling the signal at intervals as short as 25 billionths of a second.
"We have been working closely with Brookhaven Instruments Corporation for well over a decade now," says Dr William Meyer, of the Advanced Technology Development group, a division of GRC that contributed to PHaSE.
