The PNI particle reference sample is designed for AFM visualization of monodispersed polymer spheres. Nominal diameter of spheres is 100 nm, calibrated with TEM and AFM. The sample is used for establishing measurement methodologies as well as instrument/probe calibration.
Figure 1: The PNI particle reference sample is packaged in a dust proof plastic box and is mounted on a standard AFM metal substrate.
