Anton Paar offers two different technologies to characterize particles from the nanometer to the millimeter Range. The Litesizer series employs light-scattering technology to determine not only particle size, but also Zeta potential, transmittance, molecular mass, and the refractive index of nano- and microparticles in liquid Dispersions. The PSA series uses laser diffraction technology to measure the size of particles in both liquid Dispersions and dry powders in the micro and millimeter range. Side by side they open up a wide range of Possibilities for comprehensive particle characterization.
