Quantification of Lipophilicity of 1,2,4-Triazoles Using Micellar Chromatography
High-performance liquid chromatography (HPLC), over-pressured-layer chromatography (OPLC) and thin-layer chromatography (TLC) techniques with micellar mobile phases were proposed to evaluate the lipophilicity of 21 newly synthesized 1,2,4-triazoles, compounds of potential importance in medicine or agriculture as fungicides. Micellar parameters log k(m) were compared with extrapolated R(M0) valu...
متن کاملQuantification of tamoxifen in pharmaceutical formulations using micellar liquid chromatography.
This paper describes a micellar liquid chromatographic method used to analyze tamoxifen (TAMO) in pharmaceutical formulations, while focusing in its interesting features. Solid samples were solved in a micellar solution, irradiated at 254 nm, filtered and injected. Extraction steps were avoided and thus expediting the procedure. Tamoxifen was resolved in <5 min, using a mobile phase containing ...
متن کاملSeparation of Biojenic Amines Using Dansyl Cloride Derivatization and Mixed Micellar Liquid Chromatography
Separation of some biogenic amines via RP-HPLC using mixed micellar mobile phase was investigated. The compounds were derivatized before hand by dansyl chloride as a chromophoric reagent. Appropriate conditions for separation, were determined by studying factors such as temperature, type and percentage of organic modifier, concentration of surfactants (SDS and Brij-35) and the pH of the mob...
متن کاملassessment of the efficiency of s.p.g.c refineries using network dea
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
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...
