Q&A with Prof. Amadeo Fernández-Alba

Ping Wei powder is a type of traditional Chinese medicine used to treat digestive system diseases. Its growth in popularity has led to scientists seeking to properly identify its chemical profile.

Researchers leveraged the advantages of thermodesorption, followed by comprehensive two-dimensional gas chromatography coupled to time-of-flight mass spectrometry (GC×GC/TOF-MS), to compare and assess a variety of sampling phases for body odor.

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.
