Brookhaven Instruments 90Plus
90Plus
The new 90Plus particle sizer incorporates all you need for fast, routine, sub micron measurements. Based on the principles of Dynamic Light Scattering (DLS), most measurements only take a minute or two. The built-in PC computer has ample power for the Windows™-based software. Choose from the standard 35 mW laser for strong scatterers, or the avalanche photo diode for weak scatterers. And, at the time of manufacture, or as a future upgrade, add the BI-Zeta option for zeta potential measurements.
Two Scattering Angles:
Most measurements will be made at the 90° scattering angle, however, the user may select the 15° detection angle where measurements are more sensitive to larger particles.

Typical Applications:
Many everyday industrial processes and products involve dispersions. The dispersed phase is often in a state of fine subdivision. The technology to produce these dispersions, to ensure that they perform according to specifications and to solve problems which may arise in production or use, requires a knowledge of the particle size. The 90Plus can handle virtually any type of submicron sample suspended in, or dissolved in, a liquid. Some examples are
- Polymer latexes
- Pharmaceutical preparations
- Oil/Water and Water/Oil emulsions
- Paints and pigments
- Inks and toners
- Cosmetic Formulation
