Online Particle Size Distribution Analysis
Ankersmid offers
systems for Particle size analysis and taylored
solutions for on-line and add-line particle size and shape analysis.
Particle Counting Analysis
A complete range of analysers and sensors are available which can be configured to measure particles in liquid streams. Typically used where liquid cleanliness levels are important, such as hydraulic fluids and pharmaceutical fluids.

-
Electrozone measurement, sizes and counts both organic and inorganic materials, rapid measurement of particle diameters from 0.4 to 1200 µm
Particle Shape Analysis
A synchronous strobe light source and a video microscope continuously captures images of the particles in motion. Full particle classification by maximum, minimum, diameters, area, perimeter, aspect ratio and shape factors are possible.
Ankersmid offers
systems for Particle analysis, particle size and particle
shape monitoring with laser, supplying the latest In-Lab particle analysers
and taylored
solutions for on-line and add-line particle size and shape analysis.
Surface Area and Pore Size Analysis
Surface area and pore size distibution based on physisorption (adsorption and desorption of gases) may use either the dynamic or static gas adsorption systems.

Pore Size and Density Analysis
Mercury intrusion porosimetry is based on the intrusion of a non-wetting, non-reactive fluid into a porous material at selected pressures.
Micromeritics AutoPore IV
Series
- Mercury intrusion analysis providing pore size distribution as well as skeletal and bulk density values. Analytical range 0.003 to 360 micrometres.
Chemisorption
Chemisorption of metals and other surface active materials is a two step process. Firstly, the sample needs to be reduced completely to form the active metal phase. The second step involves precise gas dosing to measure the surface activity. This is called static volumetric analysis. Micromeritics offer three systems for
Chemisorption.
- Micromeritics AutoChem 2910
- The AutoChem 2910 Automated Catalyst Characterisation System performs a full array of highly precise, temperature-programmed and chemisorption studies.
- Micromeritics ASAP
2020C
- Full chemisorption analysis using the advanced flow-thru sample tubes (patented).
Density
Gas pycnometers measure volume and density using the gas displacement technique. Careful control of temperature and gas pressures yield highly accurate results.
Absolute Density
Micromeritics AccuPyc 1340
Automatic absolute density of powders.
- Micromeritics MultiVolume 1305
- Semi automatic variable sample volume.
Envelope Density
- Micromeritics GeoPyc 1360
- Automatic absolute density of powders.
Tap Density
- Micromeritics GeoPyc 1360
- Automatic tap density of powders.
Zeta Potential
The stability of a slurry or emulsion is determined by its Zeta Potential, which is the net effective charge between particles. Micromeritics
offer zeta potential analysers.
- Micromeritics 1202
- Concentrated samples up to 50% solids.
Image Analysis
The analysis of particles from both a qualitative and quantitative aspects must include image analysis techniques. Image analysis is also A powerful tool for the measurement and characterisation of many biological and natural materials.
