Triglycerides in Vegetable Oils using Gas Chromatography
Fats and oils are parts of normal daily consumptions and are considered as important nutrients in human diets. Almost all of commercially fats and oils of animal or plant origin consist of the lipid class called triglycerides (or triacylglycerols). GC is one of the most employed analytical techniques for analyzing lipid and fatty acids content of vegetable oils. Here are reported profiles of different vegetable oils triglycerides analysis, using efficient short MEGA-SE52 GC column; the use of shorter columns with Cold On-Column injection type allows to minimize the thermal degradation of these compounds thus permitting a correct quantification.

Tips & Tricks GPC/SEC: How to Care for your GPC/SEC Instrument
Columns are at the heart of a gel permeation/size-exclusion chromatography (GPC/SEC) system. Software is used to evaluate the data, to understand and present the results, and to act as an interface between the analyst and the system. But what about GPC/SEC pumps, injection systems, and detectors? They should run uninterrupted 24/7, without the analyst having to think about them or to deal with them, but these components also need care. Following some simple rules can give better results in less time. |

| UCT Abalonase™ Purified Beta Glucuronidase Formula |
Waters |
UCT is excited to expand upon its enzyme hydrolysis line with the introduction of Abalonase™ and Abalonse™+, purified Beta-glucuronidase formulas. Within minutes of application, ultra-pure Abalonase™ can deconjugate the major metabolites of interest including benzodiazepines, opioids, cannabinoids (naturally occurring and synthetic) and steroids. Rapid Hydrolysis Buffer is included with every order of Abalonase™ and Abalonse™+ to maximize the performance of the enzyme and to significantly reduce sample preparation times..

TSKgel Amide-80 for UHPLC |
Markes’ suite of thermal desorption instruments for GC analysis of VOCs and SVOCs range from single-tube manual systems through to automated multi-tube or multi-canister platforms. All these instruments bring enhanced productivity, reduced running costs and confidence in data, whatever the application – courtesy of the wide-ranging innovations developed by Markes, which include single-run analysis of C2–C44, cryogen-free operation, and quantitative sample re-collection for re-analysis.

TSKgel Amide-80 is now available in 2 micron particle size. For years, TSKgel Amide-80 columns are used successfully for HILIC separations of polar compounds such as saccharides, glycans, oligosaccharides, or peptides. The amide chemistry is particularly popular for glycosylation analysis of proteins. The new small particle size columns deliver higher resolution and peak capacity and are ideally suited for UHPLC and UHPLC-MS.
