The space is no bigger than a good-sized office break room. On beige counters along the walls and on an island in the center sit off-white rectangular boxes that could be copiers or printers. But the several hundred thousand dollars of highly sensitive scientific equipment in this room — and others like it — will be [Read More...]
As a mass spectrometrist who has migrated into the realm of clinical chemistry, I frequently tell my clinical chemistry colleagues that mass spectrometrists want to take over the world. Although an exaggeration, this statement is seldom challenged, probably in recognition of the many positive ways that mass spectrometry already has influenced the clinical laboratory and [Read More...]
Study finds that GC-MS changes or destroys sample compounds DEGRADING EXPERIENCE LC-MS peaks from analyses of a small-molecule sample maintained at room temperature (bottom) and heated for five minutes at 250 °C (top) differ considerably. If you’ve used gas chromatography-mass spectrometry (GC-MS) to analyze unknown compounds from cells and biological tissue, a new [Read More...]
The determination of water content in solvents, alcoholic beverages and various consumer products such as foods, pharmaceuticals, fuels, and petroleum products is one of the most common types of chemical testing. Many techniques such as gravimetric analysis, Karl Fischer Titration, near infra-red spectroscopy, gas chromatography (GC) and others have been used for water quantification with [Read More...]
Introduction Nowadays, the cultivation of grapes is widely spread around the world with an estimated surface area of 7.6 million of hectares in 2014 [1]. Grape production is an important activity due to the high nutritional properties of grapes and their ancient domestication leading to a large variety of by-products [2]. Grapes are consumed both [Read More...]
