Identification of PCR Products Using PNA Amphiphiles in Micellar Electrokinetic Chromatography

Separation of preservatives in cosmetic products by micellar electrokinetic chromatography.

This paper describes the methodological optimization and validation of a simple micellar electrokinetic chromatography for the rapid simultaneous separation of 2-methyl-4-isothiazolin-3-one, methylparaben, ethylparaben, propylparaben, and butylparaben. By using a 30 mM phosphate buffer (pH 7.2) containing 30 mM sodium dodecyl sulfate (SDS), an applied voltage of 10 kV and a separation temperatu...

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...

Analysis of oseltamivir in Tamiflu capsules using micellar electrokinetic chromatography.

A simple and rapid micellar electrokinetic chromatography (MEKC) method was developed for the analysis of an antiviral drug, oseltamivir, and its hydrolyzed product in Tamiflu capsules. Background electrolytes consisted of boric acid 10 mM, pH 10, and sodium dodecyl sulphate (SDS) 40 mM. The limit of detection (LOD) and limit of quantification (LOQ) of oseltamivir were 1.7 and 8.0 microg/ml, re...

Retention indices in micellar electrokinetic chromatography
