The Malvern HPPS covers a wider application range than three conventional dynamic light scattering systems. The patented technology incorporated in the Non-Invasive Back-Scatter optics (NIBS™) enables high sensitivity and high concentration measurements over an exceptionally wide size range from 0.6nm to 6000nm diameter.

  • A higher sensitivity than a dedicated instrument for samples as dilute as 0.1ppm
  • The high concentration range of back-scatter optics up to 20 vol% to simplify sample preparation
  • A wider range of applications than covered by a classical dynamic light scattering system
