The intuitive graphical user interface supports the execution of reliable, meaningful measurements. PAQXOS provides graphical presentations, tables or paper reports that can be chosen from a variety of predefined and fully customisable formats. A step-by-step wizard with built-in expert knowledge also leads the inexperienced user to successful measurements.
Dynamic light scattering size range software#
It combines our collective particle sizing expertise in a user-friendly application software which is realised as a network-ready 64-bit software for Windows® environments. PAQXOS is the joint control and evaluation platform for all Sympatec systems. Thus new opportunities for characterization in previously uncharted fields, such as particle-particle interactions and changes in dynamic viscosity, are easily accessible. No matter if the particles have been stabilised with electric charges, polymers or surfactants, NANOPHOX reliably provides information on aggregation or agglomeration behaviour. NANOPHOX proves its specific performance for stability analysis of steric or electrostatic stabilising in high-concentrated nanodispersions. With a precisely controlled temperature range from 0☌ to 90☌ the behaviour of nanodispersions can be observed or influenced, respectively. This remarkably broad concentration range is possible due to the combination of PCS and PCCS in a single instrument. Using a 30 mW semiconductor laser and Avalanche photo diodes minimum sample concentrations of just 10 -4 % by volume are measurable. The size analysis is independent of concentration and masters high concentrations up to approximately 20 % by volume. NANOPHOX covers the vast particle size range of 0.5 nm to 10,000 nm. In pharmacy and biochemistry nanoparticles serve as API carriers or can be charged with molecules for targeted drug delivery. Typical applications comprise polymer suspensions and emulsions, pharmaceutical emulsions, inks and research on nanomaterials in general. NANOPHOX is ideally suited for research and development as well as for industrial quality control. Differentiating measurements of agglomeration and sedimentation behaviour as well as about special effects like particle-particle interactions and changes in viscosity of high concentrated samples thus become feasible. The amplitude of the cross-correlation function, which depends on the multiple scattering, provides direct measurement of changes in particle number and size. The application of cross-correlation technology allows the calculation of the particle size distribution by eliminating the effect of multiple scattering. Nanoparticle size, size distribution and polydispersity are as reliably analysed with this method of dynamic light scattering as are the stability of dispersion. NANOPHOX brings Photon Cross-correlation Spectroscopy (PCCS) to life, which allows for high resolution nanoparticle size analysis in high concentrated suspensions and emulsions ranging from 0.5 nm to 10,000 nm with minimum sample preparation. In general, the acquisition of scattered light intensities of particles under thermal motion is deployed for nanoparticle characterisation (principle of dynamic light scattering (DLS)).
