Fiber Analysis with Flow Imaging Microscopy

Geometry can play a crucial role in the performance of fibers in different applications. Shape factors that influence performance include length (i.e. size of the longest dimension of the fiber), width (i.e. size of the shortest dimension), and curl. Despite the importance of fiber geometry, many conventional particle sizing measurements struggle to accurately capture the morphology of these particles.

McCrone Associates Adds FlowCam to their Suite of Analytical Instruments

The analytical lab at McCrone Associates (Westmont, IL) specializes in materials characterization and identification of particle contaminants and microscopic defects in a wide range of industrial and pharmaceutical materials. 

Historically, McCrone has not focused on enumeration. Their strengths have been in identifying materials at the micro- and nanometer scale using a variety of analytical techniques. With the addition of FlowCam to their analytical lab, they can now expand their enumeration capabilities by supplementing their current process with size distribution and concentration data. Additionally, morphological results from FlowCam will be directly correlated with the traditional microscopy-based results and identifications thereby enhancing the quality and statistical accuracy provided by particle enumeration projects. 

“There is great value in seeing images of the particles and of the actual contaminants,” says Dr. Craig Schwandt, Director of Industrial Services and Senior Research Scientist at McCrone Associates. “It allows us to identify particle type and particle source via morphology, which increases the strength of the finding.”

Purdue University Uses FlowCam Nano to Study Atmospheric Aerosols' Effect on Climate Change

The Alexander Laskin Research Group at Purdue University is a "multi-disciplinary experimental group with research interests in the areas of Analytical and Physical Chemistry of airborne and aquatic environmental particles, driven by the overarching goals of understanding their impact on the environmental chemistry, the air pollution, and the Earth’s climate."

The environmental particles studied by the Alex Laskin group can have natural and anthropogenic sources including oceans, deserts, volcanoes, transportation emissions, aviation, fire retardants, explosion disasters, and even household cooking. These particles often have multiphase chemistry, meaning they can change shape, size, and chemical composition. Particles below 2.5 µm are considered respirable and are able to enter the lungs, bloodstream, and brain.

FlowCam for the Characterization of Abrasive Compounds

Superabrasives, such as micronized diamonds and cubic boron nitride (CBN), are used extensively in applications for cutting, grinding, and drilling hard materials. The effectiveness of a particular superabrasive material in a given application is largely determined by both particle size and particle shape.

FlowCam Used to Study Algae Cultures: Training New Users on Gran Canaria

This week FlowCam Applications Scientist, Kay Johnson, visited the Canary Islands to train a new team of FlowCam users at ITC (Instituto Tecnólogico de Canarias). ITC in Pozo Izquierdo is using a FlowCam 8400 with 488nm laser to monitor marine phytoplankton. The team was originally trained by Nicole Gill when they first purchased the FlowCam in 2019, but this year a new group of scientists from Italy and Serbia have joined their team.

Using Flow Imaging Microscopy to Assess Properties of Pollutive Dryer Lint

The FlowCam has been used in marine and freshwater applications since its invention in 1999. Since then, it has been found to be valuable across many industries to evaluate microparticles of importance in medicine, manufacturing, and environmental disciplines. Rarely do we see these applications cross paths - where man-made particles are being analyzed in marine and freshwater environments. One example of this intersection is the study of microplastics, and the problems they cause for our oceans and marine life.

Using Flow Imaging Microscopy to Enhance Particle Analysis of Printer Toner

An interview with Steve Bowen, Director of Sales, Yokogawa Fluid Imaging Technologies

What is particle analysis?

Particle analysis involves taking a sample of a substance and analyzing the individual particles of the sample. The basic goal is to determine the constituents of a mixture and to differentiate between particles in the sample. Typical measurements of particles that are of interest include: particle size distribution, particle count, various measurements of particle shape, and particle concentration.
