Root exudates—substances secreted by living plant roots—are challenging to sample, as they are typically extracted using artificial devices and can vary widely in both quantity and composition across plant species.

University of Valladolid scientists used a miniaturized method for analyzing biogenic volatile organic compounds (BVOCs) emitted by tree species, using headspace solid-phase microextraction coupled with gas chromatography and quadrupole time-of-flight mass spectrometry (HS-SPME-GC–QTOF-MS) has been developed.

In this installment, we will review the fundamental terminology and data analysis principles in benchtop GC–MS. We will compare the three modes of analysis—full scan, extracted ion chromatograms, and selected ion monitoring—and see how each is used for quantitative and quantitative analysis.
