Double-headed amphiphile-based sponge droplets: synthesis, characterization and potential for the extraction of compounds over a wide polarity range
(Elsevier, 2022)Supramolecular solvents (SUPRASs) are gaining momentum in the multi-residue analysis of liquid samples thanks to the delimited hydrophilic and hydrophobic microenvironments in their nanostructures. In this work, SUPRASs ... -
A Novel Brominated Triazine-based Flame Retardant (TTBP-TAZ) in Plastic Consumer Products and Indoor Dust
(ACS, 2014)The presence of a novel brominated flame retardant named 2,4,6-tris(2,4,6-tribromophenoxy)-1,3,5-triazine (TTBP-TAZ) is reported for the first time in plastic parts of consumer products and indoor dust samples. TTBP-TAZ ... -
Direct probe atmospheric pressure photoionization/atmospheric pressure chemical ionization high-resolution mass spectrometry for fast screening of flame retardants and plasticizers in products and waste
(Springer, 2014)In this study we develop fast screening methods for flame retardants and plasticizers in products and waste based on direct probe (DP)-atmospheric pressure photoionization (APPI) and atmospheric pressure chemical ionization ... -
Novel Analytical Methods for Flame Retardants and Plasticizers Based on Gas Chromatography, Comprehensive Two-Dimensional Gas Chromatography, and Direct Probe Coupled to Atmospheric Pressure Chemical Ionization-High Resolution Time-of-Flight-Mass Spectrometry
(ACS, 2013)In this study, we assess the applicability of different analytical techniques, namely direct probe (DP), gas chromatography (GC) and comprehensive two-dimensional gas chromatography (GCxGC) coupled to atmospheric pressure ... -
Tunable solvency mixtures of tetrahydrofuran: water for efficient and fast extraction/clean-up of trace contaminants
(Elsevier, 2019)In this study, we investigated the potential of mixtures of tetrahydrofuran (THF) and water as tunable solvents for the microextraction of contaminants in solid and in liquid matrices. These two miscible solvents have very ...
