How Can Chromatography Help You Sleep Better?

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...]

Dogs vs Chromatography — Who is the Winner?

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...]

Heated Dispute Over Analytical Method

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...]

Device Merges Gas Chromatography, Mass Spectrometry

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...]

Mixing Water and Gas: The Quantitative Measurement of Water by Gas Chromatography Using Ionic Liquid Capillary Columns

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...]
