Whether you like a good ten hours, or you can cope with just six a night — we all need sleep. The average person spends nearly a third of their life asleep in fact. And most sleep takes place on your bed — or more specifically — on your mattress. People tend to invest in [Read More...]
Man’s best friend helps us in all kinds of ways. Assistance dogs for people with sight problems; dogs who can help to detect explosives; and search and rescue dogs who help us to find people who are lost. Now a researcher at the University of Melbourne in Australia has found another way that our canine [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...]
A new universal petrochemical analyzer combines the speed of ballistic gas chromatography (GC) with the ability of high-pressure mass spectrometry (HPMS) technology to identity molecules at lower limits. Officials with Boston-based 908 Devices Inc. are seeking to “democratize” chemical analysis with mass spectrometry by freeing it from its Achilles heel, the complex vacuum pumping system. [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...]
Most laboratories that use gas chromatography (GC), have at least one GC hyphenated with a mass spectrometer (GC-MS) these days. GC-MS has added advantages over GC detectors in that it provides a third dimension of data in the form of a mass spectrum. The sum of the abundance of all ions at each scan number [Read More...]
