New Study from Osaka University Compares FlowCam, MFI, and iSpect Data

In order to gain the most comprehensive understanding of particles in their samples, researchers often employ several instruments as part of their overall particle analysis scheme. Different technologies will assess different physical attributes of the particles and thereby offer scientists complementary data that are useful in validating their analyses. Even when two instruments perform essentially the same analytical technique, measurement differences between platforms may reveal physical property aspects that would otherwise go unnoticed.

FlowCam Analysis of Particle Concentrations to Monitor Water Quality in Pre and Post-Treated Drinking Water

We'll be attending the annual Water Quality Technology Conference in Cincinnati, OH, next month. On Wednesday, November 16th, at 10:30 am, Polly Barrowman will be presenting a case study with Hunter Adams, (the Water Quality Supervisor at the City of Wichita Falls Cypress Environmental Laboratory) about their implementation of flow imaging microscopy. Polly and Hunter demonstrate how monitoring particle concentrations and morphology using FlowCam at various points in the treatment system enabled Hunter's team to address elevated particle counts.

Featured FlowCam User: Skidaway Institute of Oceanography

The Skidaway Institute of Oceanography, an internationally renowned marine science research institute located on the northern end of Skidaway Island near Savannah, Georgia, has been using FlowCam since 2016. We recently spoke with Elizabeth Szink, a 2022 graduate of the University of Georgia. She had the opportunity to participate in a summer internship in Dr. Natalie Cohen’s lab at Skidaway. She was happy to share with us some highlights of her internship.

FlowCam Used to Detect CyanoHABs in African Fish Farms

Freshwater aquaculture is gradually becoming common practice in sub-Saharan Africa. Rural farmers raise fish in ponds for subsistence, to boost their family’s protein intake, and to earn supplemental income to help pay to send their children to school. Cyanobacterial harmful algal blooms (CyanoHABs) in these ponds, and in general, are starting to gain attention in Africa, as they can impact livestock and human health.

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.”

Joint Aquatic Sciences Meeting Brings FlowCam Users Together to Share Research

In May 2022 our FlowCam Aquatic Team attended the Joint Aquatic Sciences Meeting (JASM) in Grand Rapids, Michigan. This historic meeting brought together scientists from nine different societies to form the largest gathering of its kind in history. It was a welcome change after two years of virtual meetings and limited in-person collaboration.

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.

FjordFlux Cruise Uses FlowCam to Analyze Glacier Particles and Assess Effects of Climate Change

FlowCam user Jochen Wollschläger of Germany's University of Oldenburg recently returned from a research trip aboard the RV METEOR as part of the FjordFlux Cruise in the Beagle Channel, at the southernmost tip of Chile and Argentina. The goal of the expedition was to utilize the fjords of Patagonia to understand better how climate change will affect similar environments in Antarctica. Carried out in the context of the DYNAMO Project, the cruise was a cooperation between Germany, Chile, and Argentina.

Preventing Embolism from Medical Implants by Using FlowCam Imaging Particle Analysis

In a recent paper from Rostock University Medical Center, authors Anja Kurzhals et al. summarize a study they performed to determine the relevant morphological characteristics of particulates shed by a commercially available coronary stent delivery system. Flow Imaging Microscopy (FIM), also called Dynamic Image Analysis (DIA), was used to image and analyze particles produced during a simulated implantation of the cardiovascular device.
