If you needed one more reason to think about the long-term dangers of per- and polyfluoroalkyl substances, known as PFAS, this could be it: the European Environment Agency describes PFAS as “forever chemicals” – highly persistent and bioaccumulative compounds that have been used in various industrial and consumer products for decades, leading to their extensive …

LC/MS/MS is perhaps one of the most common bioanalytical methods used today, offering ultrasensitive detection in the several parts per million, and sometimes billion, range. The unique specificity of tandem mass spectrometry provides greater flexibility for LC separations, expanding the applications that can utilize LC/MS/MS. It is used in a variety of applications including environment …

In 2023, the U.S. EPA’s Fifth Unregulated Contaminant Monitoring Rule (UCMR 5) will go into effect, requiring all public water systems (PWS) serving more than 3,300 people and 800 randomly selected smaller water systems to begin testing for 29 PFAS compounds and lithium. Before UCMR 5 sampling begins, the Safe Drinking Water Act (SDWA) will …

Leonardo da Vinci once said, “Water is the driving force of all nature.” In this case, Leonardo proves wise beyond measure. All humans depend on water for drinking, sanitation, and hygiene. We use it to prevent disease and stay healthy. We need it for our food sources, commerce, and industry. Yet, we are in a …

The mining industry impacts water resources through the heavy use of water for processing and through water pollution from discharges and seepage from tailings or waste rock impoundments. PerkinElmer’s John Martin, Environmental Segment Marketing Manager, recently moderated a one-on-one with Dr. Upmanu Lall, Director of the Columbia Water Center at Columbia University. Watch the interview …

In this Q&A, Suneet Chadha, VP and GM of Applied and Food Markets, PerkinElmer, Inc., discusses how this global company …

Since their development in the 1940s, PFAS (per- and polyfluoroalkyl substances) have been utilized in industrial applications due to their chemical stability, thermal stability, and high resistance to degradation. PFAS chemicals have been named “forever chemicals,” because they are extremely persistent, lasting thousands of years.  Significant attention has placed PFAS as a rapidly emerging environmental and …

The presence of per- and polyfluoroalkyl substances (PFAS) in products used every day by millions of people is a growing cause of concern among both consumers and scientists. PFAS are considered “forever chemicals” and known to cause serious health issues in animals and humans. A deeper understanding of what they are and how they impact …

If you study pollutants in the air and water or control food or beverage quality, you’re probably familiar with a GC detector and know quite a bit about Gas Chromatography (GC). This article is for the rest of us. Those who may be a little familiar with the term but could use a really good …

A conversation with Dr. Scott Coffin, California State Water Resources Control Board Recently, the State of California announced its intention to require microplastics testing be done to protect its drinking water supplies. California often plays the Canary-in-a-Coal-Mine role on environmental issues – bringing critical questions to the forefront that impact all testing labs, not just …
