Columbia University researchers recently led an inventive three-year study at a university-affiliated hospital, redefining how we monitor pathogens, with powerful implications for many other high-risk settings.
Traditionally, wastewater surveillance has been used at municipal treatment plants to monitor disease trends across entire cities. But while useful, this wide-angle view can’t pinpoint exactly where outbreaks are starting—or how to stop them quickly.
That’s where building-level testing changes the game.
By zeroing in on a single hospital, or hospital quadrant, they demonstrated how localized wastewater surveillance offers a sharper, more actionable view of pathogen dynamics. This study revealed early warning signs of pathogen outbreak spikes, sometimes up to a week before clinical tests caught on, thanks to frequent sampling paired with electronic health records.
The composition and purity of the carbonic esters and additives in electrolytes are critical factors for maintaining battery quality and performance.
This application note shows how the compact, yet rugged Brevis GC-2050 can easily conduct this routine analysis, achieving high separation performance and good repeatability, and demonstrating its effectiveness as an easy-to-use tool for this essential QC analysis.

Scientists measure bacterial growth in laboratories across the world but why is it so universal? This article looks at bacterial growth and discusses how microplate readers can be used to advance different experiments and applications.
This application note describes the results from simultaneously analyzing 40 PFAS components using the LCMS-8050RX as target compounds after automatic sample preparation.
Good recovery rates and reproducibility results were achieved even when evaluating recoveries with 1/4 of the final MCL concentrations.

Minimal inhibitory concentration or MIC is a crucial analytical parameter often used in the control of microbial growth by antimicrobial agents. The MIC is typically defined as the lowest or minimum antimicrobial concentration that inhibits visible microbial growth in artificial media after a fixed incubation time and is often expressed in micrograms per milliliter (μg/mL) or milligrams per liter (mg/L).
It is not the only metric used to look at the effects of antimicrobials on microorganisms. The inhibitory concentration associated with 50% effect (IC50) 2 and the minimal bactericidal concentration, the lowest concentration of an antimicrobial drug that is bactericidal, are also used in different scenarios.
This article looks at some of the different applications including its use in the study of antimicrobial agents.
Researchers have different technology options available for absorbance measurements. This blog compares spectrometers and monochromators. What’s the difference?
The fundamental observation that almost all molecules in nature absorb and emit light at different wavelengths has driven developments in spectroscopy and fueled discoveries across scientific disciplines. Today researchers have access to technologies and instruments that use different forms of light to generate precise measurements of how much of a particular substance is present in a solution. These technologies are also useful in identifying molecules, analyzing the composition of samples, and studying molecular properties and processes. Light can be readily used to quantify the concentrations of substances such as nucleic acids, proteins and other molecules. It can also be deployed to measure the activities of enzymes or assess the levels of contamination in biological samples.
