Shimadzu Scientific Instruments has added two integrated liquid chromatography systems to its HPLC and UHPLC line—the Prominence-i and Nexera-i. Combining enhanced functionality, an intuitive operating environment and full automation, the series provides performance and an efficient workflow for conventional to ultra-high-speed analysis. The systems feature innovative, intuitive and intelligent design so users can begin building the lab of the future.
Restek has developed a new certified reference material (CRM) of four PAHs—benz[a]anthracene, benzo[a]pyrene, benzo[b]fluoranthene, and chrysene—designed for greater convenience, longer shelf life and increased long-term accuracy. Its high 1,000 µg/mL concentration gives analysts the freedom to dilute as needed for greater control and more economical custom mixes.
Agilent Technologies’ 5100 Inductively Coupled Plasma – Optical Emission Spectrometer (ICP/OES) allows customers to run samples faster, using less gas and without compromising performance on even the toughest samples. The instrument is ideal for labs doing food, environmental and pharmaceuticals testing, as well as mining and industrial applications.
METTLER TOLEDO’s Non-alcoholic Beverage Solution Guide suggests best practices for chemical analyses used in this ever-expanding beverage arena, helping producers meet quality goals while protecting their brand, as well as manufacturing profit margins. Examples in the guide range from correct pipetting to multiparameter systems covering analytical concerns that help maintain product reputation, taste and safety.
Using certain electronic cigarettes at high temperature settings could potentially release more formaldehyde, a cancer-causing chemical, than smoking traditional cigarettes does, new lab tests suggest. The research does not prove a health risk— it involved limited testing on just one brand of e-cigarettes and was done in test tubes, not people.
Taking antibiotics for diarrhea may put travelers visiting developing parts of the world at higher risk for contracting superbugs and spreading these daunting drug-resistant bacteria to their home countries. This is according to a new study that calls for greater caution in using antibiotics for travelers’ diarrhea, except in severe cases.
Research combining experimental work and detailed molecular simulations has revealed, for the first time, the complex role that water plays in collagen— a protein that is a component of tendons, bone, skin and other structural tissues in the body.
Upending decades-old dogma, a team of scientists say enzymes— long categorized as promoting cancer— are, in fact, tumor suppressors and that current clinical efforts to develop inhibitor-based drugs should instead focus on restoring the enzymes' activities.
Scientists recreated the energy released from an extraterrestrial collision with Earth that occurred around the time that dinosaurs became extinct. They found that the intense, but short-lived, heat near the impact site could not have ignited live plants, debunking the theory that the impact led to global firestorms.
On Nov. 12, 2014, the Rosetta mission made history when its Philae lander touched down on the surface of comet 67P/Churyumov-Gerasimenko. While this exciting technical achievement gained lots of headlines, it was only the beginning for researchers back on Earth who are receiving and analyzing comet data. The latest chapter in the story provides the closest and most detailed look at a comet that scientists have ever seen.
As many as 1.4 million Americans suffer from inflammatory bowel disease. A new study has demonstrated that mice deficient for a component of the immune system, a protein called MyD88, are more susceptible to contracting a severe IBD-like illness.
In the largest collaborative study of the brain to date, a global consortium of 190 institutions has identified eight common genetic mutations that appear to age the brain an average of three years. The discovery could lead to targeted therapies and interventions for Alzheimer’s disease, autism and other neurological conditions.
New research provides further evidence that the benefits of fish consumption on prenatal development may offset the risks associated with mercury exposure. In fact, the new study suggests that the nutrients found in fish have properties that protect the brain from potential toxic effects of the chemical.
A developer has knocked over the Westinghouse atom smasher east of Pittsburgh but plans to preserve the structure no matter what happens to the property it was on. The brick building at the base of the five-story, light bulb-shaped atom smasher was in too much disrepair to save.
Researchers who are building the highest-resolution map of the Greenland Ice Sheet to date have made a surprising discovery: two lakes of meltwater pooled beneath the ice and then rapidly drained away. One lake once held billions of gallons of water and emptied to form a mile-wide crater in just a few weeks. The other lake has filled and emptied twice in the last two years.
