Company History

Brookhaven Instruments was founded in 1981 by Dr. Bruce Weiner, a physical chemist, and Dr. Walther Tscharnuter, a physicist. The two met in 1970 as postdoctoral associates working under Prof. Ben Chu at Stony Brook University, who was leading one of the only laboratories in the world at that time investigating Dynamic Light Scattering (DLS).

 

The 1980s

Here is a look at how the 80’s shaped the future of Brookhaven Instruments

  • 1981: The company was founded by Dr. Bruce Weiner, a physical chemist, and Dr. Walther Tscharnuter, a physicist
  • The original BI-200SM goniometer used photomultiplier tubes instead of modern avalanche photodiodes. The 2030AT correlator required a specially designed interface instead of the standard readily available USB interface we use today. All of the measurement software ran on MS-DOS and PC-DOS!
  • Brookhaven Instruments pioneers high-resolution particle sizing with the DCP and XDC centrifuge.
  • The BI-8000AT correlator was housed in a 40 lb. computer with a 20 lb. monitor. It came equipped with a whopping 20MB hard drive and utilized 5 1/4″ floppy disks.The BI-90 was one of Brookhaven’s earliest particle sizing instruments. Originally, data could not be saved digitally; measurements had to be printed on a dot matrix printer. A later upgrade allowed the BI-90 to interface with an IBM-AT compatible computer, giving it the ability to view and recall measurements.

 

The 1990’s

The 90’s brought many new products to the Brookhaven lineup.

  • 1991: The first single-board correlator, the BI-9000AT.
  • 1993: First combined DLS instrument for sizing and ELS, electrophoretic light scattering, for zeta potential.
  • 1994: First backscatter DLS instrument commercially available for concentrates, the FOQELS.
  • 1998: First instrument to combine four light scattering technologies in one instrument – DLS, ELS, SLS, and PALS – for protein, nanoparticle and polymer characterization.

 

The 2000’s

Innovation lead the way in the 2000’s for Brookhaven Instruments.

  • 2002: Small-volume, flow-through, fixed angle SLS instrument, the BI-MwA, for Size Exclusion Chromatography.
  • 2009: ParSEC, a full-featured Chromatography software package.
  • 2010:  Particle Solutions, an integrated software package for running DLS, SLS, ELS, & PALS in one instrument.
  • 2010: Brookhaven becomes part of the Nova Instruments LLC family.
  • 2013: Combining backscatter for protein and nanoparticle sizing, 90º for colloid sizing, and 15º for zeta potential, three angles in one instrument in the NanoBrook Omni.
  • 2021: Brookhaven Instruments celebrates its 40th anniversary!
