Summary: High-performance thin-layer chromatography is a promising technique for high-throughput separations. The sample preparation is crucial to control matrix interferences and improve the detectability of target compounds. Recent trends have shifted towards bioassays and mass spectrometry. Traditional methods are being replaced by automated instrumental approaches for faster and streamlined sample processing. Liquid-liquid extraction is commonly used, although solid-phase extraction is gaining popularity. Planar solid-phase extraction is increasingly used for complex samples. Factors driving current interest include faster and simpler sample workflows, analysis of more complex samples, and the determination of minor contaminants with high concentration factors.

Summary: The present study compared three different liquid chromatography modes for the qualitative analysis of nusinersen metabolites and found that hydrophilic interaction liquid chromatography detected the smallest number of metabolites. The response of mass spectrometry was higher for ion pair chromatography compared to reversed-phase chromatography. Various extraction methods were used, and it was found that hybridization allowed selective extraction of nusinersen analogs while weak ion exchange-based extraction was highly efficient.

Summary: Interfacial properties, such as interfacial mass transfer, play a crucial role in the design and optimization of industrial separation processes. This study investigates the interfacial behavior of two quaternary systems and the relationship between interfacial enrichment and mass transfer. By combining the Concentration Gradient Theory (CGT) with the Koningsveld-Kleintjens (KK) model, the interfacial tension and interfacial concentration profiles are calculated. The results show that interfacial mass transfer in quaternary systems can be accurately modeled by adjusting a single additional binary mobility coefficient, and indicate a potential link between interfacial enrichment and interfacial mass transfer.
