Summary: SBSDME is a novel microextraction technique that combines the principles of SBSE and DSPE, dispersing magnetic (nano)material into the sample solution through horizontal stirring, leading to improved extraction efficiency. It offers advantages of shorter extraction times and simplified processing in a single approach.

Summary: Nitroaromatic compounds were used in explosives during world wars and may still be present in the environment. A method for determining 28 nitroaromatic compounds in water was developed using stir bar sorptive extraction (SBSE), enabling sensitive quantification. The study detected up to 16 different nitroaromatic compounds in groundwater samples, with 2,4-DNT and 1,3-DNB showing the highest concentrations.

Summary: This study optimized and compared the techniques of stir bar sorption extraction (SBSE) and multi-stir bar sportive extraction (mSBSE) for analyzing the volatile composition of grape must. The results showed that SBSE provided higher extraction of volatile compounds than mSBSE. The best conditions for SBSE were determined to be headspace extraction, 500 rpm speed, 6 hours extraction time, 60 degrees C temperature, and sequential NaCl addition.

Summary: Three compounds (2-acetyl-1-pyrroline, 2-acetyltetrahydropyridine, and 2-ethyltetrahydro-pyridine) have been identified as responsible for mousy off-flavor in wines. A simple method for quantifying these N-heterocyclic compounds simultaneously by SBSE-GC-MS was developed. This method provides lower detection and quantification limits compared to previously published concentrations in spoiled wine.

Summary: The study demonstrates that differences in aroma, taste, color, and texture of different types of soy sauce are mainly due to variations in country of origin, production process, and ingredient ratios. While soy sauce can now be produced without microorganisms for a shorter and cheaper process, there may be a loss of flavor. Analyzing volatile compounds using SBSE-GC-MS technology can identify significant differences between fermented and non-fermented soy sauces.

Summary: In this study, a molecularly imprinted polymer (MIP)-coated stir bar for recognizing diazepam was prepared. The MIP was synthesized using methacrylic acid as a functional monomer, diazepam as a template, ethylene glycol dimethacrylate as a crosslinker, and azobisisobutyronitrile as an initiator. The resulting polymer-modified stir bar was characterized and used in a stir-bar-sorptive-extraction (SBSE) method in combination with ion mobility spectrometry (IMS) or ultra-high performance liquid chromatography coupled to mass spectrometry (UHPLC-MS/MS). The MIP-SBSE coupled with UHPLC-MS/MS showed satisfactory results in quantifying traces of diazepam in water samples, while the MIP-SBSE using IMS exhibited high sensitivity for rapid screening of the compound in different matrices.

Summary: Biosorption using phosphorylated hazelnut shell waste (FHS) is a promising method for lithium removal and recovery. This study investigated the performance of a continuous-flow packed-bed column system using FHS for ultra-low level lithium removal. The results showed that the lihium biosorption capacity of the FHS column was unaffected by the bed height, but decreased with increasing flow rate.

Summary: In this study, an ionic covalent organic framework (iCOF) surface grafting monolithic sorbent was prepared for in-tube solid-phase microextraction (SPME) of aristolochic acids (AAs) in various samples. The density of quaternary ammonium ions in the iCOF was modulated for enhanced adsorption of AAs. The iCOF surface grafting monolithic sorbent was confirmed by different means. Several operating conditions were optimized to develop the online in-tube SPME-HPLC method, which showed good linearity, low limits of detection, and high recoveries for AAs in serum samples. This study presents a feasible approach for the application of COF-based monolithic sorbents in sample preparation.

Summary: A chitosan-alginate sponge with multiple cross-linking networks was developed for adsorption and enrichment of anionic dyes from food samples. The sponge showed better three-dimensional network structure, mechanical behavior, and stability compared to pure chitosan and alginate sponges. The adsorption performance and selectivity of the sponge were systematically studied, and it maintained high adsorption capacity and selectivity for anionic dyes. The sponge also showed satisfactory reusability and was successfully combined with high-performance liquid chromatography for the enrichment and detection of anionic dyes in candy and cocktail samples.

Summary: Analysis of in vivo exposure to traditional Chinese medicine using mass spectrometry is helpful for identifying effective ingredients and developing new drugs. This study focused on Forsythia suspensa (Lian Qiao) and used metabolomics technology to explore its in vivo exposure. By comparing the differences before and after administration, a complete set of nontargeted analysis strategies for TCM exposure was established. The study identified 393 Lian Qiao-related chemical components in mice after administration, including prototypes and metabolites. This study provides a reference for research on the active ingredients of Lian Qiao in vivo.
