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.

FlowCam Can Assess Cell Viability Using Fluorescein Diacetate (FDA) Stain

Determining whether algal cells are alive or dead is useful for a variety of applications including, but not limited to: wastewater analysis, algaecide testing, mesocosm experiments, and ballast water monitoring. Viability staining is a common approach used in flow cytometry to evaluate the relative abundance of live and dead cells in a sample. The FlowCam 8400, equipped with a laser, digital camera, and 2 channels of fluorescence detection, can be paired with various fluorescent stains to assess the viability of algal cells. Here we will describe how to pair an example of one such stain, fluorescein diacetate (FDA), with the FlowCam 8400 equipped with a 488nm blue laser.

Expanded Marine Taxonomic Libraries for the FlowCam

After fielding many requests from FlowCam users, we are happy to announce that we have made available expanded taxonomic libraries. These example libraries illustrate some common genera found in Casco Bay (in the Gulf of Maine) and show examples of how users may organize libraries for their own unique area. The 42 libraries cover 37 different taxa.

FlowCam Used for Analysis of Diazotrophic Organisms in High-Nitrogen Water

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.

An Integrated Approach to Monitor Taste and Odor Producing Cyanobacteria: a Webinar

"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. "Use an Integrated Approach to Monitor Algal Blooms" Opflow Dec 2018
