GC–MS

In a new study, researchers used GC–MS and LC–MS were used to detect composition fraud in food supplement creation.

Environmental polycyclic aromatic hydrocarbons can prove dangerous if metabolites enter human systems. A new gas chromatography-based approach was developed to analyze the hydroxy derivatives in wastewater samples.

Discover a novel GC-based method for accurately analyzing organic carbonates in lithium-ion batteries without the need for complex calibrations.

A gas chromatography–mass spectrometry-based approach was created and optimized to analyze reaction products of partial isobutane oxidation.

New gas chromatography-based approaches were tested for detecting volatile organic compound (VOC) emissions for binders used in mineral wool insulation products.

Monitoring the quality of essential oils is vital for protecting consumer health. Researchers recently combined gas chromatography and mass spectrometry approaches to gather data on mandarin essential oils.

As a precursor to the Lindau Nobel Laureate Meetings, Texas A&M University held a meeting for future Lindau attendees to highlight the institution’s scientific facilities. One such attendee is Caitlin Cain of the University of Michigan, one of LCGC International’s 2024 Rising Stars of Separation Science.

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.
