Researchers from Dow Chemical Company (Midland, Michigan) used headspace sampling with gas chromatography to analyze the concentration and identity of compounds in the vapor above six ionic liquids at a temperature of 100 ?C.

JASCO and Princeton Chromatography have announced a collaboration in the areas of Supercritical Fluid Chromatography (SFC) instrumentation and column manufacturing.

Scientists from Taiwan have developed a method for dispersive liquid-liquid microextraction of ionisable compounds that renders it compatible with reversed-phase HPLC by combining it with in-syringe back extraction. The new system was demonstrated with the removal of the drug clenbuterol from water.

Supercritical fluid chromatography or subcritical fluid chromatography (SFC) is considered a normal-phase technique. In this article, we sought to examine whether it was feasible to use nonpolar columns (for example, C18) under SFC conditions to separate compounds that closely eluted or co-eluted by gradient and isocratic reversed-phase high performance liquid chromatography (HPLC).

The advantages of mass spectrometry (MS) in combination with gas chromatography (GC), in terms of providing both qualitative and quantitative information, are well known. However, reliable identification and accurate measurement of trace toxic and odorous species at the lowest levels of interest can be compromised by chromatographic anomalies such as column bleed, extended solvent tails, air and water interference, and unresolved sample matrix components. To address this issue, a new software algorithm has been developed for reprocessing stored GC-MS data. It uses an innovative dynamic approach to distinguish and eliminate background interference as it changes throughout a run.
