Supramolecular solvents for making comprehensive liquid-liquid microextraction in multiclass screening methods for drugs of abuse in urine based on liquid chromatography-high resolution mass spectrometry
(Elsevier, 2023)Multiclass screening methods involving hundreds of structurally unrelated compounds are becoming es- sential in many control labs and research areas. Accurate mass screening of a theoretically unlimited number of chemicals ... -
Drugs of abuse in tap water from eight European countries: Determination by use of supramolecular solvents and tentative evaluation of risks to human health
(Elsevier, 2022)Recent research findings have confirmed the presence of illicit drugs in tap water from some European Union (UE) member states. Contaminants in tap water come directly from drinking water sources such as rivers or ... -
Towards harmonised criteria in quality assurance and quality control of suspect and non-target LC-HRMS analytical workflows for screening of emerging contaminants in human biomonitoring
(Elsevier, 2021)Although the exposure assessment of chemicals of emerging concern (CECs) has taken a decisive step forward through advances in (bio)informatics, statistics, and the development of highly sophisticated analytical instruments, ... -
Screening of additives in plastics with high resolution time-of-flight mass spectrometry and different ionization sources: direct probe injection (DIP)-APCI, LC-APCI, and LC-ion booster ESI
(Springer, 2016)Plastics are complex mixtures consisting of a polymer and additives with different physico-chemical properties. We developed a broad screening method to elucidate the nature of compounds present in plastics used in ... -
Tailoring composition and nanostructures in supramolecular solvents: Impact on the extraction efficiency of polyphenols from vegetal biomass
(Elsevier, 2022)Polyphenols are one of the most appreciated antioxidants nowadays. Industry has an enormous interest in their efficient extraction from vegetal biomass, but most of current methods are neither eco-friendly nor cost-effective. ...
