Beckman Coulter Delsa(TM) Nano Zeta Potential and Submicron Particle Size Analyzer

The DelsaNano series is a new generation of instruments that use photon correlation spectroscopy (PCS), which determines particle size by measuring the rate of fluctuations in laser light intensity scattered by particles as they diffuse through a fluid, for size analysis measurements and/or electrophoretic light scattering (ELS), which determines electrophoretic movement of charged particles under an applied electric field from the Doppler shift of scattered light, for zeta potential determination.

The DelsaNano series has a broad range of capabilities, including conventional static and automatic titration measurements for both size and zeta potential distributions of suspended particles in a wide range of size and concentration. The DelsaNano also can measure zeta potential of a solid surface or film.

The DelsaNano series includes the following models:

  • DelsaNano S: Size analysis - 0.6 nm - 7µm
  • DelsaNano C: Size and zeta potential measurement of particles in liquid suspension or zeta potential measurement of solid surfaces
  • DelsaNano AT: Optional accessory for the automatic titration of sample suspensions. Titration range from pH 1 to pH 13

Key Features:

  • High sensitivity size and zeta potential measurement for particles from 6 Angstrom to 7 micron in suspension with concentration ranging from 0.001% to 40%.
  • Patent-pending FST technology
  • Fully automatic pH or additive titration for both size and zeta potential measurement
  • Zeta potential measurement of solid surface or film
  • Easy to follow standard operating methods (SOMs)
  • Multi-component standard operating procedures (SOPs)
