FlowCAM® : A Digital Imaging Particle
Analyzer for Measurement and Characterization of Particulate
Matter Most particle analyzers only give you a “count” of
particles and a single measurement, “diameter”. Usually referred to as
“Equivalent Spherical Diameter”, or ESD, this measurement is based upon
measuring something proportional to volume, and then deriving “diameter” by
assuming that volume is contained in a spherical shape. While this may be useful
for calculating a “particle size distribution”, it certainly does not tell the
whole story, as shown in Figure 1(첨부화일 참조). FlowCAM® is an imaging-based
particle analyzer that takes a digital image of each particle, and records up to
26 different measurements (size, shape and spectral) for each particle
simultaneously. Using the included VisualSpreadsheet© software, the particles
can then be sorted and filtered based upon these measurements just as one would
do in a spreadsheet, except that the results are displayed visually in the form
of images alongside the tabular results. Powerful statistical pattern
recognition algorithms can be employed to automatically separate different
particle types found in a heterogeneous sample. FlowCAM® combines the speed
of automated particle analysis systems with the ability to distinguish
individual particles found in microscopy. Wherever you used to use a microscope,
you can now use FlowCAM to acquire, measure and classify up to 50,000
particles/minute, giving you greatly increased statistical confidence in your
data. FlowCAM will complement other quantitative particle analysis data with
image-based data that lets you actually see the results for visual verification
and interpretation. As the first to market with this technology, and with
over 12 years of continued leadership, Fluid Imaging Technologies, Inc. is the
resource to rely on for imaging particle analysis technology. We invite you to
take us up on a free FlowCAM sample evaluation: we will run a sample of your
material through the instrument and interactively show you the results via the
web. You will see the actual images of your sample particles, and be able to see
how VisualSpreadsheet© can sort, filter and classify each particle. Many of our
prospects have learned something new about their process(es) just from this
simple free analysis. We are convinced that once you see the results with your
own samples, you will want a FlowCAM in your lab!
