Determination of linezolid and its achiral impurities using sweeping preconcentration by micellar capillary electrophoresis

Advances in the theory and application of MEEKC

“…Alternatively, zwitterionic organic buffers such as TRIS may be used [48]. An increase in buffer concentration has been shown to enhance resolution factors.…”

Development of new reference material neohesperidin for quality control of dietary supplements

“…Numerous methods have been used for quantitative determination of organic substances, including high‐performance liquid chromatography (HPLC), gas chromatography (GC), nuclear magnetic resonance (NMR), high‐performance anion‐exchange chromatography, capillary electrophoresis and differential scanning calorimetry (DSC) . However, the differences in response factors of the purified substance and impurities upon the detectors may result in systematic errors of purity.…”

Sweeping under controlled electroosmotic flow and micellar electrokinetic chromatography for on-line concentration and determination of trace phlorizin and quercitrin in urine samples

“…While it provides highefficiency separations, the detection limits are higher due to the small sampling volume. A number of on-line concentration strategies have been developed, for example, field amplified sample stacking [1][2][3], isotachophoresis (ITP) [4,5], dynamic pH junction [6,7], pH-mediated stacking [8][9][10], and sweeping [11][12][13]. Sweeping is an effective and convenient way for doing on-line sample concentration in MEKC.…”
