Development of hybrid monoliths incorporating metal–organic frameworks for stir bar sorptive extraction coupled with liquid chromatography for determination of estrogen endocrine disruptors in water and human urine samples

Microchimica Acta, Journal Year: 2022, Volume and Issue: 189(3)

Published: Feb. 7, 2022

Abstract A novel coating based on hybrid monolith with metal–organic framework (MOF) onto conventional Teflon-coated magnetic stir bars was developed. For this purpose, the external surface of Teflon bar firstly vinylized in order to immobilize a glycidyl methacrylate (GMA)–based polymer magnet. Then, an amino-modified MOF type MIL-101 (NH 2 -MIL-101(Al)) covalently attached GMA-based monolith. After synthesis process, several parameters affecting extraction target estrogens by sorptive (SBSE) including pH, ionic strength, time, stirring rate, desorption solvent, and time were also investigated. The resulting evaluated as SBSE sorbent for three (estrone, 17β-estradiol, estriol) synthetic 17β-ethinylestradiol from water human urine samples followed HPLC fluorescence detection (excitation emission wavelengths, 280 310 nm, respectively). Under optimal experimental conditions, analytical figures method established, achieving satisfactory limits range 0.015–0.58 µg L −1 , recovery results ranging 70 95% RSD less than 6%, precision values (intra- inter-extraction units) below 6%.

Novel materials and approaches for solid-phase (micro) extraction in LC-MS-based metabolomics

TrAC Trends in Analytical Chemistry, Journal Year: 2024, Volume and Issue: 180, P. 117941 - 117941

Published: Aug. 30, 2024

Metabolomics offers a unique approach to study biological systems. Liquid chromatography coupled mass spectrometry serves as powerful analytical tool analyze complex mixtures of metabolites. However, successful metabolomic analysis relies on sample preparation. While untargeted traditionally favors non-selective procedures like liquid-liquid extraction (LLE), these methods can compromise performance due limited analyte enrichment and potential matrix interferences. Solid-phase (SPE) has emerged well-established versatile technique for this purpose, offering advantages over other traditional LLE. This review explores the applications SPE solid-phase microextraction (SPME) in LC-MS-based metabolomics. We discuss various modes SPE, ranging from conventional flow-through cartridges plates approaches involving dispersion sorbent sample, well sorbents, their properties, diverse geometries support materials employed SPME. underscores emerging protocols further accelerate metabolomics research.
