COULTER^® N4 Series Control Samples

N4 Series Size Controls are for use with the COULTER® N4  SD, COULTER® N4  MD, and COULTER® N4 PLUS photon correlation spectroscopy submicron particle size analyzers. All N4 Series controls consist of latex particles. N4 Series controls should be selected based on the size range of interest. The assay is performed at a scattering angle of 90° making it also suitable for checking the performance of other PCS instruments.
