Interaction Parameters of Surfactant Mixtures by Inverse Gas Chromatography
(IntechOpen, 2012)
The Inverse Gas Chromatography (IGC) has been used in the measurement of surfactant-surfactant interaction parameters at different percentages and temperatures in cationic surfactant mixtures. Specific retention volume ...
Combined use of gas chromatography and HPLC-ESI-Q-TOF to assess the culinary uses of archaeological Santa María style ceramic vessels from El Colorado (Catamarca, Argentina)
(Springer, 2020-06-01)
In this paper, an interdisciplinary investigation was carried out to study if Santa María tricolor style vessels were used as culinary equipment in a 14th century AD domestic cooking space in El Colorado (Yocavil valley, ...
Development and validation of LC-MS-based alternative methodologies to GC–MS for the simultaneous determination of triterpenic acids and dialcohols in virgin olive oil
(Elsevier, 2018-01)
Pentacyclic triterpenes are minor, but very relevant compounds found in virgin olive oil (VOO). A rapid and reliable LC-MS method for determining the triterpenic acids and dialcohols (after ultrasound assisted extraction) ...

Simple approach based on ultrasound-assisted emulsification-microextraction for determination of polibrominated flame retardants in water samples by gas chromatography-mass spectrometry
(Elsevier Science, 2009-01)
A simple, efficient, innovative and environmentally friendly analytical technique was successfully applied for the first time for the extraction and preconcentration of polybrominated diphenyl ethers (PBDEs) from water ...
Coacervative microextraction ultrasound-assisted back-extraction technique for determination of organophosphates pesticides in honey samples by gas chromatography–mass spectrometry
(Elsevier Science, 2010-10)
Coacervative microextraction ultrasound-assisted back-extraction technique (CME-UABE)is proposed for the first time for extracting and preconcentrating organophosphates pesticides (OPPs) from honey samples prior to gas ...

(Elsevier Science, 2009-05)
A novel and efficient analytical methodology is proposed for extracting and preconcentrating polybrominated diphenyl ethers (PBDEs) from samples of environmental interest prior gas chromatography-mass spectrometry (GC-MS) ...
Ultrasound-assisted leaching-dispersive solid-phase extraction followed by liquid-liquid microextraction for the determination of polybrominated diphenyl ethers in sediment samples by gas chromatography-tandem mass spectrometry
(Elsevier Science, 2010-06)
Ultrasound-assisted leaching-dispersive solid-phase extraction followed by dispersive liquid-liquid microextraction (USAL-DSPE-DLLME) technique has been developed as a new analytical approach for extracting, cleaning up ...
Non-targeted discovery of class-distinguishing metabolites in Argentinian pacu fish by comprehensive two-dimensional gas chromatography with principal component analysis
(Elsevier Science, 2021-05)
Pacu fish are an important source of revenue and food supply in Argentina, however the nutritional effects of raising these fish in an integrated rice-fish farming environment on the fish metabolome are still unclear. To ...
