Gas Chromatography (GC)

Many multi-column gas chromatography systems use two-position multi-port switching valves, which can suffer from delays in valve switching. Shimadzu researchers aimed to create a new sampling and switching module for these systems.

As the push for green chemistry continues to grow, University of Almeria researchers created a review for ways chromatographic techniques could be more environmentally friendly.

LCGC International spoke to Adrián de la Fuente and Silvia Valverde Bastardo from the University of Valladolid, Spain, about the development of a miniaturized headspace solid-phase microextraction gas chromatography–quadrupole time-of-flight mass spectrometry (HS-SPME-GC–QTOF-MS) method for the analysis of biogenic volatile organic compounds (BVOCs) emitted by native Spanish trees.

Flavonoids are widely used metabolites that carry out various functions in different industries, such as food and cosmetics. Detecting, separating, and quantifying them in fruit species can be a complicated process.
