Ternary separations in liquid-liquid chromatography: Which mode when?

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 ...

Rethink your liquid-liquid separations

Efficient liquid-liquid separations are an integral part of many industrial processes. Water entrained in oil and other hydrocarbon products can impede quality specifications. Entrained oil in process water streams puts additional demands on effluent treatment systems. Under the present economic environment, processing production demands push plants and existing equipment beyond the original de...

Optimizing separations in online comprehensive two‐dimensional liquid chromatography

Online comprehensive two-dimensional liquid chromatography has become an attractive option for the analysis of complex nonvolatile samples found in various fields (e.g. environmental studies, food, life, and polymer sciences). Two-dimensional liquid chromatography complements the highly popular hyphenated systems that combine liquid chromatography with mass spectrometry. Two-dimensional liquid ...

Microscale liquid phase separations.

Miniaturization and microfabrication of analytical instrumentation for chemical and biological analyses has been proceeding at a rapid pace for a few decades, and has gained momentum in the past decade with the introduction and application of microfabricated instruments. Motivating factors for performing microscale separations and analyses are reduced reagent, solvent and sample consumption, re...
