Benefits of Collision Cross Section (CCS) data obtained by UPLC-ESI-IMS-QTOF MS and GC-APGC-IMS-QTOF for small molecules identification in screening applications
Sociedad Española de Cromatografía y Técnicas Afines (2022)The coupling ion mobility separation to high-resolution mass spectrometry (IMS-HRMS) techniques, usually hyphenated with liquid or gas chromatography (LC/GC), are advanced tools for wide-scope screening for a large ... -
Effective Ion Mobility and Long-Term Dark Current of Metal Halide Perovskites with Different Crystallinities and Compositions
Wiley (2022-12)Ion transport properties in metal halide perovskite still constitute a subject of intense research because of the evident connection between mobile defects and device performance and operation degradation. In the case of ... -
Effects of structural characteristics of (un)conjugated steroid metabolites in their collision cross section value
Elsevier (2023-05-08)In this work, the collision cross section (CCS) value of 103 steroids (including unconjugated metabolites and phase II metabolites conjugated with sulfate and glucuronide groups) was determined by liquid chromatography ... -
LC-IMS-HRMS for identification of biomarkers in untargeted metabolomics: The effects of pterostilbene and resveratrol consumption in liver steatosis, animal model
Elsevier (2023)Untargeted metabolomics with the combination of ion mobility separation coupled to high resolution mass spectrometry (IMS-HRMS) was applied to investigate the impact of resveratrol and pterostilbene supplementation on the ... -
NORMAN guidance on suspect and non-target screening in environmental monitoring
Springer (2023-09-04)Increasing production and use of chemicals and awareness of their impact on ecosystems and humans has led to large interest for broadening the knowledge on the chemical status of the environment and human health by suspect ... -
Pseudopeptidic host adaptation in peptide recognition unveiled by ion mobility mass spectrometry
Royal Society of Chemistry (2022-12-07)Complexation of the glutamic–tyrosine–glutamic tripeptide (EYE) with a series of pseudopeptidic cages has been thoroughly investigated using different analytical techniques. The stoichiometry and affinities of the ... -
Technosols designed for rehabilitation of mining activities using mine spoils and biosolids. Ion mobility and correlations using percolation columns
Elsevier (2017-01)The restoration technologies in areas degraded by extractive activities are more efficient under the use of their own spoils. Reducing deficiencies in physical properties, organic matter, and nutrients with a contribution ... -
The relevant role of ion mobility separation in LC-HRMS based screening strategies for contaminants of emerging concern in the aquatic environment
Elsevier (2021-05-05)Ion mobility separation (IMS) coupled to high resolution mass spectrometry (IMS-HRMS) is a promising technique for (non-)target/suspect analysis of micropollutants in complex matrices. IMS separates ionized compounds based ... -
Ultra-Performance Liquid Chromatography-Ion Mobility Separation-Quadruple Time-of-Flight MS (UHPLC-IMS-QTOF MS) Metabolomics for Short-Term Biomarker Discovery of Orange Intake: A Randomized, Controlled Crossover Study
MDPI (2020)A major problem with dietary assessments is their subjective nature. Untargeted metabolomics and new technologies can shed light on this issue and provide a more complete picture of dietary intake by measuring the profile ... -
Use of ion mobility-high resolution mass spectrometry in metabolomics studies to provide near MS/MS quality data in a single injection
John Wiley and Sons (2021-03-10)The use of ion mobility separations (IMSs) in metabolomics approaches has started to be deeply explored in the last years. In this work, the use of liquid chromatography (LC) coupled to IMS-quadrupole time-of-flight mass ...
