Particle Surface Area Analyzer

The AcornTMArea is a revolutionary instrument designed to measure the surface area of particles or droplets dispersed in any type of liquid. This new generation (patented) technique is based on nuclear magnetic resonance (NMR) and offers many advantages in comparison with conventional first generation surface area instrumentation.


Measurements with the Acorn Area are simple and easy. Suspensions and emulsions can be measured non-invasively, without dilution. One ml of the dispersion is placed in a glass vial and then inserted into the sample chamber. The test sequence is initiated with a key stroke and within minutes, the proprietary AreaQuantTM software algorithm reports the total measured surface area.

Principle of Operation: The liquid in contact with the surface of a particle behaves differently from that of the bulk, or "free" liquid and this effect can be detected through NMR relaxation and diffusion measurements. The AreaQuant software differentiates that behavior and quantifies the surface area from these measurements.


The Acorn Area Advantage:

This particle size analyzer is small, lightweight and portable, yet robust

No moving parts and no adjustments are necessary

Acorn Area particle surface area analyzer is designed for use in the R&D or the QC laboratory

Compatible with XP, Vista or Windows 7




The Acorn Area works with a wide range of materials in virtually any liquid including:

Ceramics & Refractories
Cosmetics & Personal Care
Household goods
Pigments and Fillers
Inorganic/Organic Powders
Porous materials


It is the ideal choice for fast analysis of solid or liquid particles of any size or shape and works up to high solids concentrations.


With the Acorn Area the particle surface area measurement time is minimal - no sample preparation and no clean-up means significantly increased sample throughput. Important processes such as milling or grinding can be monitored in virtually real time.
