GC-MS
As the ongoing search for helium continues worldwide, the community of analytical chemists often finds itself entangled in the debate of helium versus hydrogen in the field of gas chromatography
Because drugs tend to be small-molecule structures, gas-chromatography-MS (GC-MS) serves as confirmation both for alcohol level and for most drugs.
Dr. Susan Rae Anderson is an independent consultant in analytical chemistry at S.R. Anderson Consulting (formerly Olin Corporation).
Portable technology remains as rugged, reliabile, fast, and easy as ever.
Serge Cremers, Pharm. D., PhD, is an associate professor at Columbia University Medical Center and an attending clinical chemist at New York Presbyterian Hospital. He is the director of the Clinical Pharmacology and Toxicology Laboratory at Columbia University Medical Center and the director of the Biomarkers Core Laboratory of the Irving Institute for Clinical and Translational Research, which is home to Columbia University’s Clinical and Translational Science Award (CTSA) and the largest mass spectrometry facility at Columbia University, focusing on targeted metabolomics and the measurement of drugs. Dr Cremers’ areas of expertise are bio-analytical chemistry, translational and clinical pharmacology, therapeutic drug monitoring, as well as clinical chemistry of metabolic bone diseases. He conducts research in all of these areas and has published over 90 papers.
Sports is big business, which is why leagues and federations are desperate to keep their franchises honest. In the US, Major League Baseball (MLB) received a record $9 billion in revenues in 2014, while the National Football League took in close to $10 billion.
European laboratories testing feed and food for dioxins and dioxin-like substances now have lower-cost, smaller-footprint alternatives to high-resolution mass spectrometers (HRMS) for confirming levels of the toxic contaminants, thanks to a new European Union regulation.
Criminals are smuggling an estimated $30 billion in U.S. currency into Mexico each year from the United States, but help could be on the way for border guards, researchers reported recently. The answer to the problem: a portable device that identifies specific vapors given off by U.S. paper money.
The warm beauty of amber was captivating and mysterious enough to inspire myths in ancient times, and even today, some of its secrets remain locked inside the fossilized tree resin. But for the first time, scientists have now solved at least one of its puzzles that had perplexed them for decades. Their report on a key aspect of the gemstone’s architecture appears in the ACS journal Analytical Chemistry.
