Voyaging into the Single Nano Region

The IG-1000 Plus Single Nano Particle Size Analyzer:
Going Beyond the Single Nano Region and into the Sub-Nano Region

IG-1000 Plus uses the induced grating (IG) method, which is based on a new principle for measuring
the size of nanoparticles using the phenomenon of dielectrophoresis and diffracted light.

With light scattering, the conventional method, the light scattered by particles decreases sharply
for particle sizes of less than 100 nm. Furthermore, in the single nano region (i.e., particle sizes of
less than 10 nm), there are physical restrictions that make it difficult to detect scattered light, and
the measurement of particle sizes also becomes difficult. The IG method does not use scattered
light; as a result, it is free from these physical restrictions, and does not require the input of the
refractive index as a measurement condition. It therefore allows the size of nanoparticles to be
measured simply and with high sensitivity, and is particularly effective in the analysis of single
nanoparticles.
