FlowCam^® - Flow Imaging Microscopy Blog

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. 

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.

Yokogawa Fluid Imaging Technologies was recently named as one of the 2020 Best Places to Work in Maine. This list is made up of 84 companies in three size categories: small (15-49 U.S. employees), medium (50-249 U.S. employees) and large (250+ U.S. employees).

An article featured this month in the American Water Works Association (AWWA) publication Opflow describes the challenges currently facing water utilities across the country, and lays out a strategy to proactively monitor for cyanobacteria and taste & odor causing algae.

This year, in lieu of their annual conference and exhibition, Powder & Bulk Solids hosted a virtual conference: The Powder Show: Digital Flow.

Steve Bowen, Yokogawa Fluid Imaging Technologies Director of Sales, presented a short webinar at this event, titled "Measuring Sphericity & Aggregates of Powders Dispersed in Fluids". The talk is still available to view, alongside other presentations, on The Powder Show website.

On Tuesday, October 13th, at 3pm CDT, Yokogawa Fluid Imaging Sales Director, Steve Bowen, will be presenting a webinar on Flow Imaging Microscopy at the NAPIM (National Association of Printer Ink Manufacturers) Fall Technical Conference, part of InkWeek 2020.

A long-term study undertaken by Chaffin et al. at Ohio State University monitored nutrient levels and phytoplankton growth in the Lake Erie central basin from 2014 until 2017. The purpose of the study was to determine the primary limiting nutrient determining phytoplankton growth, and determine if multiple limiting nutrients existed during this time period. The FlowCam was used to image and analyze phytoplankton species and to estimate biomass and biovolume of the species under consideration.

"Most drinking water utilities enter high-alert mode upon testing positive for microcystin. Staff at the city of Wichita Falls, Texas, Water Purification Laboratory responded calmly when they received that dreaded phone call in July 2018 because of their progressive approach to monitoring cyanobacteria. Climate conditions are conducive to harmful algae blooms (HABs) and taste-and-odor events with increasing frequency and intensity. As a result, US Environmental Protection Agency (USEPA) regulations are moving toward requiring cyanobacteria monitoring. Proactive drinking water utilities are seeking a streamlined approach to monitoring cyanobacteria and nuisance algae." Adams et. al.

Metal Additive Manufacturing (also known as 3-D printing) requires carefully engineered compound metal powders in order to make high-quality end products. Authors Farzadfar et al. have determined a process for manufacturing a bimodal powder that has both the desired particle density and still flows freely.

We are happy to announce that we have made available curated galleries of our favorite aquatic images from around the world, in a variety of applications. Are you curious what your water samples would look like when analyzed on the FlowCam? Check out all of the images in our galleries, or peruse below for a sampling of what's available. This is only a small sampling of what the FlowCam is capable of; please contact us if you'd like to see more.
