The top 5 questions to consider when purchasing a particle analyzer

It’s no surprise that there are many technologies available for particle analysis. Particle sizing and characterization are critical components of many processes across a wide range of applications.

An imaging particle analyzer is an important instrument for; 

  • water utilities for monitoring drinking water supplies to detect odor causing algae
  • pharmaceutical companies to safeguard efficacy, safety, and immunogenicity of injectable drugs
  • food and beverage companies to ensure quality ingredients 
  • ocean researchers to study and document microscopic life in the earth's oceans

Copepod as seen in video mode on a FlowCam

On a recent visit to the Coastal School for Girls in Freeport, Maine for a classroom demonstration of the FlowCam, we captuted this video. This feisty little copepod is roughly 500µm in size. The FlowCam was operating in video mode at the time.

Detecting and monitoring HABs in an Oregon river to ensure safe water

The Oregon Health Authority recently issued a health advisory after finding high levels of blue-green algae -- in this case, anabaena -- in the Clackamas Cove portion of the Clackamas River. Thankfully, the algae bloom is about four miles past the Clackamas River Water (CRW) drinking water intakes and did not affect the drinking water. 

When algae populations explode they can create harmful algae blooms (HABs). HABs are mostly fueled by excess nutrients in area waterways from various places like agriculture, sewage treatment plants, and runoff from lawns and paved surfaces.

Why FlowCam for Micronized Diamonds?

A manufacturer of micronized diamonds used the FlowCam to ensure a new batch met their desired specifications – at least 95% of the diamond particles needed to have a uniform, smooth perimeter.

Detecting Glass Shards in Protein Therapeutics

Lew Brown has added to his ongoing work on thresholding in particle imaging. He recently published a poster at the 2015 Colorado Protein Stability Conference entitled, “Glass Shard Detection in Protein Therapeutics Using Dynamic Imaging Particle Analysis".

Dynamic Imaging Particle Analysis (DIPA) technology is being increasingly used for characterization of other transparent intrinsic particles in biologics such as protein aggregates. Lew's poster details an investigation of using DIPA technology in order to detect glass shards in a protein therapeutic, along with the protein aggregates.

Why FlowCam for Food Particle Analysis?

Taste and texture can't be directly measured, so you need to rely on “tasting panels” in order to gather information on prospective products. This is both time consuming and expensive.

Particle size, and more importantly particle shape, correlate directly to the taste and mouth-feel of food products. FlowCam can help you determine the optimum size and shape of the particles in your product, and then enable you to quickly analyze batches to ensure they meet the standard.

The Gulf of Maine Coastal Ecosystem Survey is using a FlowCam

We're excited to be participating in the Gulf of Maine Coastal Ecosystem Survey, a project over two years in the making. Starting from workshops held as part of the Gulf of Maine Integrated Ecosystem Research Program, it became clear that there was a need to gain a better understanding of ecosystem dynamics within the coastal waters of the Gulf of Maine.

Scientists help public avoid health risks of cyanobacteria

We recently learned that Professor Rolf Vinebrooke and his colleagues at the University of Alberta are using a FlowCam for early detection of cyanobacteria in lakes and other freshwater environments. Toxic algae are starting to bloom in lakes around the world - and we're not even at the height of the summer season. Increases in atmospheric temperature combined with land nutrients are promoting the growth of harmful cyanobacteria in these bodies of water, damaging for not only the associated ecosystems, but also potentially for the people who visit the lakes.

"Our ability to rapidly detect the onset of outbreaks of potentially toxic cyanobacteria provides timely information to the public regarding the major lakes throughout the province," says Vinebrooke. "If the cell counts exceed the World Health Organization guideline of 100,000 cells per millilitre, we notify Alberta Health officials, who then post advisories at the lake in question." Read the full article on Phys.org

LSU Plankton Laboratory uses dynamic imaging to study microscopic life

The commercial crawfish ponds that line the highways of Roberts Cove, Louisiana, are very busy this time of year. These waters are teeming with plankton that can’t be seen with the naked eye. The Plankton Laboratory at Louisiana State University (LSU), uses dynamic imaging particle analysis to study the microscopic life in these ponds.

Maine algae community to capitalize on growing business opportunities

While aquafarmers in Maine have been harvesting seaweed for nearly 80 years, for a variety of uses and products, in recent years wild harvests have not been able to meet market demand for some species. The Maine Technology Institute (MTI) has stepped in to provide $50,000 to help form a Maine “algal cluster” that would include those involved in both macroalgae and microalgae to help the industry take advantage of a growing market. The funds awarded under MTI’s cluster initiative program will “encourage innovation and foster growth of a sustainable, ecologically sound and profitable algal industry in Maine.”
