FLOWCAM EDUCATION
FlowCam Case Study at Water Quality Technology Conference
Polly Barrowman, our Water Markets Manager, will be presenting a FlowCam case study with Hunter Adams, the Water Quality Supervisor at the City of Wichita Falls Cypress Environmental Laboratory, this year at the annual WQTC Conference.
Polly and Hunter demonstrate how monitoring particle concentrations with FlowCam at various points in the treatment system enabled The City of Wichita Falls to address elevated particle counts that were not identified by using traditional turbidity measurements.
FlowCam LO, and other particle measuring techniques, were used to analyze the impact of surfactants like polysorbate 80 on protein aggregation during accelerated stability studies. Surfactants can degrade to generate particles detectable via FlowCam under these stress conditions as well as more realistic stresses. Shown below are images of particles observed in a phosphate-buffered saline sample containing 0.1% (v/v) polysorbate 80 following heat stress.

The 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.

Characterizing Protein Aggregation with Orthogonal and Complementary Analytical Techniques
With protein aggregates spanning a size range from nanometers to microns, several analytical techniques are required for complete particle analysis.
In our new white paper, we demonstrate how combining flow imaging microscopy, light obscuration, and dynamic light scattering provides a comprehensive characterization of aggregates and particles under different stress conditions.
Last week we hosted our partners from Yokogawa's international offices for a week-long FlowCam Training Summit. It was wonderful to meet and work in person with our international partners, many of whom traveled for the first time to Maine. Attendees came from as far away as Japan, South Korea, South Africa, Ireland, Brazil, Singapore, Bahrain, and Taiwan.
