Nanoptic 90 is a nanoparticle analyzer based on the well-known technique of dynamic light scattering (DLS). Nanoptic 90 can measure nano materials with size down to 1nm. The high-power long lifetime laser and high sensitivity PMT provide Nanoptic 90 the ability to demonstrate rapid and accurate testing results. Measurement: Particle size Particle size range: 1 to 9500nm Dispersion type: Wet Technology: Dynamic Light Scattering (DLS)
