Chemical shortage hampers ‘legal high’ work

Identification of suspect substances depends on reference materials that are in short supply.   Attempts to understand and control new synthetic recreational drugs are being hindered by analysis laboratories' inability to obtain pure samples of the compounds, experts say. The growing problem of synthetic drugs — which include mimics of cannabis and amphetamine — came [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...]
