For more than 30 years, WYATT TECHNOLOGY develops and sales characterization tools for macromolecules and nanoparticles.
STATIC LIGHT SCATTERING
Absolute molar mass (Mw) and size (Rg), online or batch mode. Detectors for "classical" SEC/GPC/Gel Filtration or UPLC/UP-SEC systems.
DYNAMIC LIGHT SCATTERING
Hydrodynamic radius (Rh) and polydisersity (Pd), online or batch mode.
Absolute (aRI) and differential (dRI) refractive index measurements, online or batch mode (dn/dc). Detectors for "classical" SEC/GPC/Gel Filtration or UPLC/UP-SEC systems.
On-line differential viscometer for measurement of the intrinsic viscosity and Mark Houwink-Sakurada parameters.
ELECTROPHORETIC MOBILITY (ZETA POTENTIAL)
MP-PALS, Massively Parallel Phase Analysis Light Scattering, for measurement of the electrophorectic mobility and determination of zeta potential of not only large particles but also proteins.
FIELD FLOW FRACTIONATION
Open channel separation with no stationary phase based on hydrodynamic volume and over a wide size range (from nanometer to micron): AF4 with different channel sizes, Frit Inlet, Hollow Fiber FFF, Electrical Flow FFF.
Automated sample preparation for GC-MALS (Composition Gradient Multi-Angle Light Scattering analysis). Measurements of equilibrium association constants, reaction rates, virial coefficients and dn/dc.
SOLARIS: UV lamp for buffer sterilization directly in your solvant chromatography bottle.
