Summary: A translucent coating based on polydimethylsiloxane and aminopropyltriethoxysilane was prepared by a sol-gel method for stir bar sorptive extraction, successfully extracting and preconcentrating organic compounds from aqueous and organic samples. The coating was characterized as homogeneous, relatively polar, and thermally and chemically stable.

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: Smoke-derived taint is a significant concern for the U.S. wine industry, particularly on the west coast, with climate change anticipated to worsen the issue. An analytical approach based on SBSE-GC-MS was proposed in this paper to quantify smoke-related volatile phenols in wines, providing a new tool for evaluating wine smoke exposure.

Summary: In this study, porous aromatic frameworks (PAFs) with different pore sizes were evaluated for their adsorption performance of polycyclic aromatic hydrocarbons (PAHs). A method using PAF-120/PDMS coated stir bar was developed for the analysis of trace PAHs in environmental samples. The results showed high recovery and accuracy of the proposed method. Various concentrations of PAHs were detected in the environmental samples.

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: 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: In this study, an improved headspace-stir bar sorptive extraction was developed to extract volatile compounds with different polarities in a short time. Extraction conditions were selected and optimized using response surface methodology, and the addition of a cold stir bar further shortened the extraction time to 1 minute. The effect of different ethanol concentrations and salt additions on extraction efficiency was also studied, and 10% ethanol concentration with no salt addition provided the highest extraction efficiency for most compounds. The feasibility of the high-throughput extraction condition was verified using volatile compounds spiked in a honeybush infusion.

Summary: Stir bar sorptive extraction is effective for trapping odorants, and this study investigated the relationship between desorption conditions and efficiency for different odorants. Four machine learning models were trained using a dataset of four desorption conditions and physicochemical properties. The Random Forest model performed the best, and its prediction value was validated using a dataset of new odorants.

Summary: A magnetic porous carbon material with Fe3C nanoparticles encapsulated in porous carbon was prepared using MIL-101(Fe) as a carbon and Fe source through one-pot pyrolysis under N-2 atmosphere. The MPC-900 material showed the highest extraction ability for sulfonamides. By systematically studying the main parameters affecting the extraction process, favorable linearity and detection limits for sulfonamides were obtained. This method can effectively extract ultra-trace compounds in complex sample matrices.

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: 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.
