With the NANOPHOX CS, Sympatec introduces a state-of-the-art DLS instrument. By combining Photon Cross-correlation Spectroscopy (PCCS) with an innovative polarisation-separated backscattering technology, the system enables nanoparticle size analysis in suspensions and emulsions at up to 100 times higher solid contents than conventional DLS. With only little sample effort, meaningful and repeatable measurements are realised under one minute of sample material in original concentration.
