N4
Plus (Multi-angle capability)

The N4 Plus is the only photon correlation spectroscopy (PCS) analyzer that uses six fixed measurement angles. Most PCS analyzer performs measurements at only 90 degree. Because sub-micro particles scatter light in patterns depending on particle size, large particles may be difficult to detect at 90 degrees if the sample contains a large number of smaller particles.
