LMR-Area

Features and advantages:


The instrument has a high degree of portability and automation, which can measure 5~10mL of samples and quickly analyze the dispersion and stability of particles.NMR is not sensitive to light, it can know the overall information of the sample, and it has no requirement on the solid content concentration of the paste, so it is suitable for dark or thick paste system.NMR can measure the wet specific surface area of particles without requiring the shape of particles, so it is particularly suitable for measuring materials with irregular shape and large surface area, such as graphene/carbon nanotubes and other new nanomaterials.

The detailed information

Nuclear magnetic resonance (NMR) is especially suitable for the measurement of ceramic slurry, battery slurry, abrasive, coal water slurry, coating and other thick dispersion systems.NMR is not light, it completely penetrates the sample and has a number of unique advantages: measurements can be made without dilution, and the shading effect associated with optical measurements is avoided.Because it measures the particle's wetted specific surface area, NMR is particularly sensitive to the smallest particles, which contribute the most to the particle's surface area.Although NMR does not directly measure particle size distribution, surface area measurements are more sensitive to true particle size distribution than optical methods that directly measure particle size distribution, because small particles scatter light weakly, making them difficult to detect with lasers.
