Nonlinear Predictive Modelling Enables In Silico Optimization of Chromatographic Methods for Complex Stationary Phase‑Analyte Interactions
To reach satisfactory results in terms of accurate retention time prediction, new in silico optimization approaches must be considered.
Evaluation of Achiral Stationary Phases for Gradient Screening with Supercritical Fluid Chromatography
Unlike reversed-phase liquid chromatography, SFC lacks a universal stationary phase. Thus, it is important to re-evaluate the default column screening library used with SFC. In this study, three uncommon achiral SFC columns were investigated and compared to three popular stationary phases.
MISER LC–MS Analysis of Teas, Soft Drinks, and Energy Drinks
In this study, we describe a simple and rapid liquid chromatography–mass spectrometry (LC–MS) method for the evaluation of caffeine, taurine, and aspartame in teas, soft drinks, and energy drinks using high performance liquid chromatography (HPLC) coupled with electrospray ionization (ESI)-MS detection and multiple injections in a single experimental run (MISER) analysis.
