Alfa Chemistry laboratories offer state-of-the-art microscopy techniques to visualize surfaces, adsorbates, nanostructures, and devices at the atomic and molecular scale. Because SPM systems interact directly with the material of interest, they are also able to go beyond imaging and probe local physicochemical properties such as friction, adhesion, stiffness/modulus, charge, and local magnetism.
Malvern Panalytical Zetasizer Nano ZS
sing Non-Invasive Backscatter optics (NIBS) it has significantly better performance than systems using 90 degree scattering optics.
In addition, a microrheology option is available for measuring sample viscosity and viscoelastic properties, as well as a Protein Measurement option for protein mobility measurements.
The flow mode option enables the system to be connected to an SEC or an FFF system to use as a detector for the size of proteins or nanoparticles.
We offer a suite of instrumentation to characterize the extrinsic properties (i.e., hydrodynamic diameter, size distribution, disperse state, agglomeration kinetics, surface charge) of nanomaterials dispersed in buffers, biological media and organic solvents and integrate intrinsic properties (i.e., primary size & size distribution, shape, (im)purity, chemical composition).
A choice of cuvettes are available, from disposable single-use to specific cells for viscous or high concentration samples or measuring the zeta potential of surfaces.
The Zetasizer Nano ZS is a high performance two angle particle and molecular size analyzer for the enhanced detection of aggregates and measurement of small or dilute samples, and samples at very low or high concentration using dynamic light scattering with 'NIBS' optics. The ZSP also incorporates a zeta potential analyzer that uses electrophoretic light scattering for particles, molecules and surfaces, and a molecular weight analyzer using static light scattering.
