Therefore, it is probable that literature, such as written … WebApr 17, 2024 · As a result, in 1984, micellar electrokinetic capillary chromatography (MEKC) was developed to separate neutral compounds [2]. This separation is achieved by the addition of ionic micelles to the electrophoretic medium. A micelle is a self-assembled, single layer particle formed from amphiphilic molecules. WebCapillary GC columns are best suited for highly sensitive assays. Capillary columns consist of a thin, fused silica glass tube in which the stationary phase is chemically bonded or coated to the inner column surface. Non-polar GC columns are best suited for the analysis of non-polar compounds (e.g. alkanes). avion plus ultra lujan
