Voters in California, Maine, Massachusetts and Nevada chose to legalize adult use of Cannabis sp. and its extracts while even traditionally conservative states like Arkansas, Florida, Montana and North Dakota enacted policy allowing for medical use. More than half of the United States [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...]
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...]
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...]
