NANOPHOX - Photon Cross-correlation Spectroscopy for size and stability analysis of nano-suspensions and emulsions from 1 nm to 10,000 nm
Photon Cross-correlation Spectroscopy for size and stability analysis of nano-suspensions and emulsions from 1 nm to 10,000 nm
In general, the acquisition of scattered light intensities of particles under thermal motion is deployed for nanoparticle characterisation (principle of dynamic light scattering (DLS)). The method known as Photon Correlation Spectroscopy (PCS) applies auto‐correlation of scattered light intensities in order to determine particle size distribution. However, this conventional technology requires extremely diluted samples in order to deliver meaningful results.
NANOPHOX brings Photon Cross‐correlation Spectroscopy (PCCS) to life, which allows for nanoparticle size analysis in turbid suspensions and emulsions ranging from 1 nm to 10,000 nm at up to a hundred times higher solid contents. In addition, stability of nano-suspensions and emulsions may be analysed. The outstanding technological feature of NANOPHOX is the acquisition of two separately induced scattered light intensities which then are cross‐correlated. This allows for robust measurement even at higher sample concentrations. Typical applications comprise e.g., pharmaceutical ingredients, ceramics, pigments, ink and research on nanomaterials in general.
