Ankersmid
is a well-renown and leading manufacturer of analytical equipment for
Particle Size and Shape analysis. We offer well over 35 years of
particle analysis
knowledge, and employs seasoned personnel with a wide scope of
experience. This
has lead to our revolutionary “EyeTech” Particle Size, Shape & Conc.
Analyzer.
EyeTech
Combined Technologies for
Particle Size, Shape & Conc. Measurement
Particle Size controls many
important product characteristics, such as:
1.Viscosity
2.Flow-ability
3.Sedimentation
4.Optical Properties
5.Impact/Compressive strength
6.Agglomeration
7.Etc.
Conventional techniques derive
particle size from a (physical) property....,
not it’s actual size!
Usually Particle Size is expressed as the diameter of a sphere with
similar
property à equivalent sphere…, but less than 1% is a spherical particle!
These diameters are fundamentally different for
the same particle.
-The equivalent diameters differ for any non-spherical material.
-Thus, every Particle Size Analysis (PSA) technique yields different
results for non-spherical materials!
EyeTech Laser Channel
LOT: Laser Obscuration Time technology
From the duration of the obscuration
(t) and the known
rotation velocity of the laser beam (v) the particle diameter
(D) can be calculated:
D = v . t
In relation to the high speed of the rotating laser, the particles
are stationary, thus will not effect particle size measurement
NO requirement’s for pre-knowledge, or:
1.Calibration
2.Refractive Index (RI)
3.Absorbance Index (AI)/Color
4.Temperature
5.Viscosity variation
6.Transparency, Mirror like.. or
7.Electrical conductivity
Advantages:
1.Data is collected on single particles
2.Detection of minor fractions
3.Direct time based measurement of correct particle size, not influenced
by
physical or optical properties!
4.Operation in liquid, dry or surface
5.No Calibration required
6.Robust measurement, no user-alignment
7.High Resolution
8.Concentration measurement (kinetics)
9.21 CFR Part 11 compliant
10.Upgradeable with Dynamic Shape analysis!
Video Channel collects digital images
used for:
1.Visualization during Laser Measurement
2.Dynamic Shape Analysis
3.Grabbing Images and Recording Movie
EyeTech Shape Analysis
Features:
1.Easy setup and measurement using software wizards
2.Advanced pre-processing algorithms
3.Size and Shape selections
4.Automated report generation
5.Storage of real raw date (un-processed images)
6.Re-processing of raw data
7.Calibration and verification tools available
8.Interface with 3rd party hardware (e.g. microscopes)
Dynamic Shape Analysis (DSA)
1. For each individual particle, size and shape parameters are
determined.
2. The EyeTech Image Analysis software automates set-up and measurement.
3. EyeTech software includes many procedures such as:
– Pre-processing procedures
– Out-of-Focus Rejection
– Morphology Operations
– Grouping according to size/shape
– (Re-)processing of stored images and movies
DSA provides a solution for characterization of non-spherical
materials:
1.Multiple size & Shape parameters to adapt to any application.
2.No assumptions about particle’s sphericity.
3.Random orientation of particles. No preferred orientation as in
microscopy.
4.Selecting of particles based upon size or shape.
5.Visualization for measurement validation/verification of Laser
results.
