Buch. Etat : Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - Bioanalysis of endogenous substances, metabolites, and contaminants poisons is important in analyses of biological functions, metabolomics, forensic toxicology, patient diagnosis and biomonitoring of human exposure to hazardous chemicals. In these analyses, methods of sample preparation are essential for the isolation and concentration of target analytes from complex biological matrices. These processes, however, are time-consuming, labor-intensive and error-prone, and markedly influence the reliability and accuracy of determining target analytes. Thus, efficient sample preparation techniques and their integration with analytical methods have become significant. Solid-phase microextraction (SPME) is a simple and convenient sample preparation technique that has enabled automation, miniaturization, high-throughput performance, and online coupling with analytical instruments. Moreover, SPME has reduced analysis times, as well as solvent and disposal costs.This book consists of 14 original, peer-reviewed papers for the Special Issue in the MDPI journal Molecules. The topics covered include headspace fiber SPME (HS-SPME) gas chromatography-mass spectrometry (GC-MS), HS-in-needle microextraction GC-MS, thin film SPME liquid chromatography-tandem mass spectrometry (LC-MS/MS), magnetic solid phase extraction LC-MS/MS, in-tube SPME LC-MS/MS and in-tube SPME LC-UV. Samples analyzed include plant-derived volatile organic compounds; body odor; metabolites in urine, plasma and saliva sample; and biomarkers of tobacco smoke exposure in hair and environmental estrogens.…

Buch. Etat : Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - Most analytical instruments currently in use struggle to directly manage complex matrices such as environmental, food, and biological samples, making sample pretreatment essential. In the analytical process from sampling to data analysis, sample pretreatment plays a vital role in extracting, separating, and concentrating target analytes. It also enhances detection, improves sensitivity and accuracy, and reduces instrument maintenance and operating costs, all of which significantly impact the reliability and accuracy of analytical results. Therefore, developing efficient sample pretreatment technologies and integrating them into various analytical instruments remains a key challenge.This reprint comprises three peer-reviewed review articles and nine original research papers contributed by research groups for a Special Issue of the MDPI journal Molecules. The topics covered include comprehensive review articles on advanced coating materials, such as metal-organic frameworks, covalent organic frameworks, hybrid graphene-based materials, and molecularly imprinted polymers. Additionally, the reprint presents various SPME and related microextraction methods employing multi-walled carbon nanotube-ionic liquid/polyaniline adsorbents, MonoTrap, covalent organic polymer mixed-matrix membranes, magnetic persimmon leaf composites, and capillary coatings as extraction materials.…
