The IG-1000 single is the first nano particle analyzer using
induced grating method, which allows you to enter sub nano
range. Thereby no cross-contaminations of foreign particles or
agglomerates disturbs the measurements. Also no refractive index
or special pH-value is required. Due to the new technology it
will be also possible to prevent time-consuming zeta-potential
measurements and to trace time-stability of the solution in its
natural wet environmental. The induced grating (IG) method, is a
new principle for measuring the size of nanoparticles using the
phenomenon of dielectrophoresis and diffracted light. With
dynamic 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 with
particle sizes of less than 10 nm, there are physical
restrictions that make it difficult to detect scattered light.
Therefore the measurement of particle sizes becomes also
difficult. The IG method uses diffracte
