Atmospheric pressure gas chromatography coupled to quadrupole-time of flight mass spectrometry as a powerful tool for identification of non intentionally added substances in acrylic adhesives used in food packaging materials

Evaluation of gas chromatography – electron ionization – full scan high resolution Orbitrap mass spectrometry for pesticide residue analysis

“…Following work on interface development [30] and first evaluations of applications [31,32] a number of publications appeared on the suitability for both quantitative and qualitative residue analysis [33][34][35][36][37][38]. In most cases TOF mass analyzers with a resolving power not exceeding 20,000 were used, but in principle higher resolving powers can be achieved when coupling to high-end (high cost) instruments, with FTICR [39] as an extreme example.…”

Analysis of Trace‐Level Volatile Compounds in Fresh Turf Crop (Lolium perenne L.) by Gas Chromatography Quadrupole Time‐of‐Flight Mass Spectrometry

“…It enables the detection and reliable identification of the compounds in the samples at very low concentration levels and has widespread application in analyzing trace-level organic compounds in the environment, food safety and toxicology. [24][25][26][27] Lolium perenne L. is an important pasture and turf crop. [28] According to literatures published, some volatile compounds have been identified in gramineae plants, while they were not identified in fresh Lolium perenne L. by GC/MS.…”

Atmospheric pressure gas chromatography–time-of-flight-mass spectrometry (APGC–ToF-MS) for the determination of regulated and emerging contaminants in aqueous samples after stir bar sorptive extraction (SBSE)

“…Applications using APGC are still scarce. Some examples are determination of PAHs and nitropolycyclic aromatic hydrocarbons (NPAH) in biological samples (mosses), as well as the analysis of acrylic adhesives [19], fruits [20], and petroleum [21]. To the best of our knowledge, there are no published studies on determination of organic contaminants in the environment using GC-APGC-ToF-MS, which could be used as an alternative to GC-MS/MS, especially for the screening of unknowns and to avoid false positives.…”

“…When APGC is used instead, ionization is heavily influenced by the presence of water traces in the source that enhance protonation processes. This results in a "softer" ionization that promotes the formation of [M + H] + ions for most compounds [19,36], including Musk R1, where m/z = 257 shows now the highest intensity (Fig. 5B).…”
