Two-dimensional shape information is essential for
the accurate characterization of non-spherical particles and aggregates. To
meet these vital needs, in the EyeTech the Laser Obscuration Time measurement is
complemented with Dynamic Image Analysis.
shape analysis channel uses a video microscope to provide an optimal image
for processing. Illumination is provided by a synchronized strobe
images can be monitored and stored as streaming live video of the sample or
processed using the EyeTech image analysis software.Enahnced
features such as rejection of out-of-focus particles, separation of touching
particles, pre-processing image filters and automatic lighting correction assist
in optimizing sample measurement.
algorithms enable automatic programmed calculation of a variety of parameters
including Ferets diameter, area, perimeter, shape factor, aspect ratio. This
two-dimensional shape and size information complements the laser analysis data
for better characterisation of non-sperical materials.
analysis allows observation as well as measurement. One can scan the sample
quickly for aggregation, contamination and proper sample preparation. Then use
the EyeTech software for measurement of significant shape features, geometric
properties and statistics.
