Use of micellar electrokinetic chromatography to measure palmitoylation of a peptide

Micellar electrokinetic chromatography.

Twenty-five years of micellar electrokinetic chromatography

Micellar electrokinetic chromatography (MEKC), which can separate neutral analytes as well as charged analytes by the capillary electrophoretic technique, was developed in 1982 and the first paper was published in 1984. The authors’ group concentrated their effort into the characterization of MEKC as a separation technique until early 1990s. Most issues in MEKC separations were successfully sol...

Retention indices in micellar electrokinetic chromatography

The use o f retent ion indices in mice l la r electrokinet ic ch roma tog raphy ( M E K C ) is eva lua ted both f rom a theoretical and a practical point o f view. F undamen t a l equa t ions for the de te rmina t ion o f retent ion indices in M E K C are descr ibed, showing that re tent ion indices are independen t o f the surfac tant concentra t ion.

Modeling The Capacity Factor of Analytes in Micellar Electrokinetic Chromatography Using Computational Descriptors

       A multiple linear regression model is proposed to calculate capacity factor of  analytes using structural features computed using HyperChem software. The  chemical descriptors of analytes were computed using HyperChem software and  regressed against the experimental capacity factors of analytes collected from the  literature. The absolute average percentage deviation (AARD) and individua...

Separation of dithiocarbamate metal complexes by micellar electrokinetic chromatography

Separation of a number of transition metal complexes with bis(2-hydroxyethyl)dithiocarbamate (HEDTC) by micellar electrokinetic capillary chromatography (MEKC) with direct photometric detection was investigated. Pre-capillary complexation was shown to be superior to on-capillary complexation in terms of the number of metals ions which could be detected and their peak shapes, enabling analysis o...
