Polycyclic aromatic compounds in air – importance of re-volatilisation from soils
GC-MS/MS and flux analysis show that soils can re-emit PAHs and related compounds, with secondary emissions potentially rivaling local primary sources.
Volatile compound fingerprinting for traditional sesame oil authentication using GC-MS with GC×GC-MS-assisted identification
HS-SPME-GC×GC-MS-assisted fingerprinting enables sensitive authentication of sesame oil, detecting maize oil dilution from 5% and essence adulteration from 0.2%.
Toward Accurate Estimation of Extractable Organic Fluorine by Analysis of Fluoride Contamination in Extracts Using Gas Chromatography
A GC-MS/MS method quantifies inorganic fluoride in EOF extracts and shows that fluoride contamination can substantially overestimate organic fluorine measured by CIC.
