Featuring interviews with industry leaders, the LCGC library is updated on a weekly basis with a different subject focus each month.
Torsten C. Schmidt of the University Duisburg-Essen in Germany recently developed an in-tube extraction (ITEX) method for headspace sampling of beer prior to gas chromatography–mass spectrometry (GC–MS). In this short video, he explains the principles of the technique and its advantages over other methods. Watch Here >>
Comprehensive liquid chromatography (LC) is a multidimensional technique that has the potential to increase peak capacity resolution when separating complex mixtures, especially in food analysis. In this new video from LCGC TV, Luigi Mondello from the University of Messina, Italy, describes the fundamental principles of 2D LC, and explains the advantages over 1D LC.
Gas chromatography (GC) is often regarded as a mature technology and some say that the application base has become routine; however, conventional detectors may not be able to keep up with the speed of separations that can be achieved today. In this new video Kevin Schug from the University of Texas Arlington, USA, talks about the development of a new vacuum ultraviolet (UV) detector, from the initial idea to the fundamentals of its operation.
Estrogen is implicated in numerous regulatory roles in the human body, and even when present at low concentrations it can have a big effect on physiological processes. Kevin Schug from the University of Texas Arlington, USA, gives the main factors to consider when analyzing different types of biological fluids and gives his advice for scientists who want to begin using 2D LC–MS–MS.
