Nuclear magnetic resonance particle size analyzer ACORN AREA™

for the pharmaceutical industryfor the cosmetics industryprocess

The ACORN AREA™ is a revolutionary instrument designed to measure the surface area of nanoparticles dispersed in a liquid. This patented nuclear magnetic resonance method offers many advantages in comparison with conventional surface area techniques. Operation principle The relaxation time of particles dispersed in a liquid is an average of the two relaxation times, weighted by the relative amount of liquid on the particle surface and that in the free liquid. This is a direct measure of the particle surface area. Acorn Area advantages Low cost Measurements without dilution No sample preparation Results in minutes Compact No moving parts Suitable for QC or R&D Simple to use Dedicated software: AreaQuant™ Measurement method To make a measurement, Place a 0.5 ml sample in a sample tube. Insert it into the Acorn Area™. The sample resides within a coil located between two permanent magnets. A static, uniform magnetic feld, B0, causes the protons within the liquid to align with B0; this process typically takes a few seconds.
