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.
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
Measurements without dilution
No sample preparation
Results in minutes
No moving parts
Suitable for QC or R&D
Simple to use
Dedicated software: AreaQuant™
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.
