Electrically actuated, pressure-driven liquid chromatography separations in microfabricated devices

Chiral Separations: Liquid Chromatography

The use of CE in the analysis of pharmaceuticals is now becoming Rrmly established as a useful complement and alternative to the more widely employed technique of HPLC. The major attractions of CE are that considerable cost and time savings are possible, especially in the areas of chiral analysis and in the determination of solutes having limited or no chromophore. The recent advent of the use ...

Microfabricated pillar array columns for liquid chromatography

Electrically-Driven Active Plasmonic Devices

Enhanced light-matter interactions in light-confining structures (such as optical cavities) have been extensively investigated for both fundamental studies and practical applications. Plasmonic nanostructures, which can confine and manipulate light down to the nanometer scale, are becoming increasingly important (Atwater 2007, Brongersma 2009). Plasmonic resonators and antennas can convert free...

High-Pressure Liquid Chromatography

An isocratic reversed-phase high-pressure liquid chromatographic method for the determination of six components of the teicoplanin complex in biological fluid was developed. By using fluorescence detection after precolumn derivatization with fluorescamine, the assay is specific and highly sensitive, with reproducibility studies yielding coefficients of variation ranging from 1.5 to 8.5% (at 5 t...
