Shimadzu Scientific Instruments introduces a particle size measurement principle called Induced Grating (IG), which allows users to measure nanoparticles with high sensitivity and reproducibility. Shimadzu's new IG-1000 particle size analyzer applies the IG method to measure single nanoparticles. The IG-1000 offers several advantages over dynamic light scattering: The sensitivity is the same when measuring a 1 nm particle or 100 nm particles; it eliminates interferences by using optical signals emitted by the diffraction grating formed by the particles; it offers a simple, three-step workflow to inject the sample, insert the electrode and begin analysis; it ensures high reproducibility, which removes the imprecision that comes with particle analysis in the single-nano range; and users can evaluate mixed samples with the IG method because the signal size does not depend on particle size.
