Low Field NMR Instrument for Complex Nanoparticle Suspension Characterisation

May 09 2022

The Mageleka Magnometer XRS is ideal for routine analysis of complex multi-component nanoparticle solid-liquid and liquid-liquid formulations using non-invasive technology based on NMR proton relaxation.

In every industrial application a knowledge and understanding of the molecular structure and dynamics at the particle-liquid interface is critical to improving or optimising suspension and emulsion product performance at every stage from initial formulation to final manufacture. The Magnometer XRS provides direct information about the extent and nature of any particle-liquid interface of suspensions and emulsions in a matter of minutes.

Measurements with the Magnometer are simple and easy, the sample is placed into a standard NMR tube and then inserted into the MagnoPod©, the test sequence is then initiated and the result reported in under 2 minutes. An exceptionally wide concentration range of 0.01% to 90+% with small sample size of 0.1mL or less and with little or no sample preparation, the Magnometer is perfect for routine analysis of particles suspended in solvents and melts regardless of shape and size. With no prior NMR experience required, the Magnometer is suitable for chemists, technicians or plant workers. The separate magnet assembly allows for remote or glove box operation, an optional programmable temperature-controlled unit is idea for environments where temperature stability is required. The technique is non-destructive so perfect for long term studies.

Applications include batch-to-batch reproducibility in a manufacturing environment, formulation development, kinetic processes, surfactant and competitive surfactant adsorption, aggregation and flocculation, sedimentation studies, presence of para- and ferro-magnetic impurities, oxygen and water content of solvents, molecular weight of polymers in solution polymer and solvent viscosity and additive studies.

Industries served include catalyst, pharmaceutical and personal health care providers, paints. Pigments and coatings, ceramics, refractories, agro chemicals, cosmetics, batteries, electronics, nano medicine and graphene/graphene oxides.
