MSU is an affirmative-action, equal-opportunity employer, committed to achieving excellence through a diverse workforce and inclusive culture that encourages all people to reach their full potential. The collectors work with 12-13mm tubes.Д¬olumn setup for transport of colloids and nanoparticles The lab has two ISCO Retriever 500 fraction collectors for continuously collecting effluent fractions in a column experiment. More detailed information can be found at the Malvern website. This functionality allows us to conveniently examine how solution chemistry influences surface charge and aggregation states of particles. In addition, our system is also equipped with a MPT-2 Multipurpose titrator that is used in conjunction with the zetasizer for automated measurements of particle size, zeta potential, or scattering intensity as a function of solution pH, conductivity, orВ additive concentrations.

Molecular weight (342 to 2x1E7 Da) by Static Light Scattering.

Zeta potential and electrophoretic mobility by Laser Doppler Microelectrophoresis.

Particle size distribution (0.3 nm to 10 microns) by Dynamic Light Scattering.

The Malvern Zetasizer Nano-ZS is a premium and popular system with the highest sensitivity and widest range of measured parameters for performing the following measurements:

Malvern Zetasizer Nano-ZS (Room 525 PSSB) The photoreactor has a 1100 cm 2 exposure area, and can be used to study physical, chemical and biological changes of samples upon light exposure. The ATLAS Suntext XLS+ photoreactorВ is an advanced benchtop xenon tester with an irradiance range of 250-600 W/m 2 at 300-800 nm wave length, measures and displays the chamber air temperature (CHT) and hasВ 10 space for custom programs. Monitoring structure development in complex fluids with time or temperature, or structure breakdown on dilution.ATLAS Suntest XLS+ phtoreactor (Room 525 PSSB).High frequency rheology of dilute systems on process-relevant timescales.The Zetasizer is available as the Zetasizer Advance range of laboratory benchtop systems (successor to the. Viscoelastic measurements of protein solutions to assess onset of protein-protein interactions and insoluble aggregate formation Zetasizer systems are also used to analyze particle mobility and charge (Zeta potential) using the technique of Electrophoretic Light Scattering (ELS), and the molecular weight of particles in solution using Static Light Scattering (SLS).Rheological characterization of therapeutic proteins and biopolymer solutions.protein-based formulations.ДЄpplications of DLS Microrheology include: Only requires microliter-scale volumes for rheological characterization of materials where sample volume is limited e.g.Probes very high frequencies necessary for characterizing inherent short timescale, viscoelastic responses (whereas mechanical techniques are fundamentally limited by inertia).For these types of materials, Microrheology offers significant advantages: DLS Microrheology is a passive microrheology technique, whereby the colloidal probe particles only undergo thermal fluctuations in a system at thermodynamic equilibrium.ДLS Microrheology is applicable for the rheological characterization of low viscosity and weakly-structured complex fluids, such as dilute solutions of polymers and surfactants through to concentrated protein formulations. Microrheology involves tracking the motion of dispersed tracer particles of known size by Dynamic Light Scattering (DLS) and determining the rheological properties of the sample using the Generalized Stokes-Einstein Relation. Rheological properties, such as viscosity and viscoelasticity, can be measured from bulk sample deformation using a mechanical rheometer, or on a micro-scale using an optical technique such as Microrheology. Rheology is the study of flow and deformation of materials.
