GC-FID/MS screening of supercritical CO2 extracts of peels from Citrus aurantium L.

2015
The peels of Citrus aurantium L. from Dubrovnik region (south Croatia) were extracted first time by supercritical CO2 (SC-CO2) at 40 °C and 10 MPa at 1.76 kg/h to obtain enriched extracts in comparison with simple pressing of the peels. The extracts were analyzed in detail by gas chromatography and mass spectrometry (GC- FID/MS).

Detection of nonylphenol isomers in sewage and sludge of waste water treatment plant by GC-FID-MS combined with deans switch

Journal of Chromatography A
Nonylphenols (NPs) are persistent endocrine-disrupting organic pollutant. Most studies focus on total NP content, with limited research on individual isomers. This study developed a method to separation and detection of 10 NP isomers using GC-FID-MS combined with Deans switch. It can effectively transfer NPs from the first gas chromatography column (DB-

Investigation of mineral-mediated photochemical processes and the development of an automated TD-GC-FID/MS system coupled to an atmospheric reaction chamber

2019
The atmospheric aqueous phase is an important reaction medium for the processing of both biogenic and anthropogenic organic compounds. Particularly, the formation of aqueous-phase secondary organic aerosol (aqSOA) and the influence on ambient air quality and regional climate are of increasing interest compared to data from comparable gas-phase ...
