In order to improve the chromatographic resolution (Rs) with a good analysis time, experimental designs were applied for multivariate optimization of the experimental conditions of an isocratic reversed phase high per...
Previous studies demonstrated that quantitative structure retention relationships (QSRR) combined with the linear solvent strength (LSS) model allow for prediction of gradient reversed phase high performance liquid ch...
In order to study the placental transfer of nucleoside reverse transcriptase inhibitors, a quick and simple reversed phase high performance liquid chromatography with tandem mass spectrometry method has been developed...
A new method based on the microwave assisted micellar extraction technique (MAME) has been optimized for the extraction of tanshinones from the traditional Chinese medicine-Salvia miltiorrhiza Bunge. Non-ionic surfact...
Vitamin A is an essential nutrient. Accurate determination of vitamin A in formulae or serum is a challenging problem, due to the labile properties of vitamin A and complexity of the matrices. For accurate and precise...
Ibuprofen was investigated with the use of reversed phase thin layer chromatography on RP2F254, RP8F254s, and RP18F254s (E. Merck), using methanol-water in different volume compositions as a mobile phase. The chromato...
A novel method based on high performance liquid chromatography with variable wavelength detection was developed for quantitative analysis of the bioactive ingredients in a Chinese herbal preparation called Kangnaoshua...
Nano alumina fibers, 2nm in diameter and approximately 0.25m long are electroadhesively grafted to a microglass fiber. A non-woven media is formed by conventional wet-laid paper making technology. The media has a high...
Using a pure silica stationary phase along with a simple acetonitrile-phosphoric acid aqueous mobile phase provides a powerful and versatile tool for the analysis of a broad range of polar compounds, such as amino aci...
Molecular interaction energy (MI) values calculated by molecular mechanics (MM2) using a model graphitic carbon phase were used to study the specificity of a graphitic carbon column. The analytes were positional isome...
