Wyatt DynaPro NanoStar Dynamic Light Scattering
The DynaPro NanoStar is a unique cuvette-based DLS instrument used for the analysis of proteins, promiscuous inhibitors, micelles, quantum dots, liposomes, metallic nanoparticles, and more. The instrument is designed to work with any standard cuvette, but can also accommodate scarce and precious samples through specially designed quartz cuvettes which afford robust, accurate measurements with as little as 1 µL of a solution, while Wyatt proprietary disposable cuvettes provide comparable sensitivity with as little as 4 µL! Coupled with the versatile and user-friendly DYNAMICS software, the NanoStar may be utilized to measure not just size, size distributions, and weight-average molar mass, but also solution properties relevant to sample stability: the second virial coefficient (A2 or B22), the diffusion interaction parameter (kD or D1, closely related to the second virial coefficient), and the temperature of protein melting or aggregation onset (TM, Tonset).
Malvern Viscotek SEC-MALS 20
The Viscotek SEC-MALS 20 is a multi-angle light scattering detector that can be used to measure the absolute molecular weight and oligomeric state of proteins, independent of retention time. It can also be used to analyze natural and synthetic polymers, including the measurement of molecular size over the widest possible range expressed as the radius of gyration, Rg. The SEC-MALS 20 multi-angle light scattering detector is connected to the output of an HPLC system equipped with an SEC column. Signals generated from the sample passing through all detectors are analyzed by OmniSEC software consisting of 20 detectors arranged around a vertical flow cell to detect scattered light at a wide range of angles. The angular intensity and concentration information is combined to construct a plot, which is used in two ways. Firstly to extrapolate the data to determine the scattered light intensity at zero angles, from which the absolute molecular weight is calculated. Secondly to determine the initial slope of the plot which is related to the radius of gyration of the molecule (Rg). This system is equipped with a Viscotek VE3580 RI detector for the accurate determination of sample concentration.
Malvern Zetasizer Nano Z
The Zetasizer Nano Z system is dedicated to the measurement of zeta potential and electrophoretic mobility in aqueous and non-aqueous dispersions using Laser Doppler Micro-Electrophoresis. It is the perfect system for measuring zeta potential and electrophoretic mobility of colloids and nanoparticles when the measurement of size or molecular weight is not required. Laser Doppler Micro-electrophoresis is used to measure zeta potential. An electric field is applied to a solution of molecules or a dispersion of particles, which then move with a velocity related to their zeta potential. This velocity is measured using a patented laser interferometric technique called M3-PALS (Phase analysis Light Scattering). This enables the calculation of electrophoretic mobility, and from this, the zeta potential and zeta potential distribution. A ‘Quality Factor’ and ‘Expert Advice System’ give the confidence of having an expert at your shoulder.
