High-temperature ultrafast liquid chromatography.

A novel liquid chromatographic system which enables high temperature ultrafast liquid chromatography (HTU-FLC) has been designed through the careful consideration of heat transfer, band broadening, and pressure drop. Studies of the effect of linear velocity on the HETP show that column efficiency at high velocity, especially of well-retained solutes, dramatically improves at higher temperatures...

Analysis of Polymer Additives and Impurities by Liquid Chromatography/Mass Spectrometry and Capillary Electrophoresis/Mass Spectrometry

The analysis of polymeric materials can be quite challenging because such samples are often of complex nature due to the presence of various groups of additives, compounding ingredients, and fillers. Of special importance are stabilizers that protect the material from degradation by thermal stress during manufacture or from environmental impact during use. Apart from intact stabilizers, the deg...

High-Performance Liquid Chromatography Determination of Methotrexate in Plasma

This article describes a simple and fast high-performance liquid chromatography method for the determination of methotrexate (MTX) in plasma. Samples were collocted from children receiving high-dose MTX at shafa Hospital (Ahvaz University of Medical sciences, Ahvaz, iran) at various times after the end of eachinfusion. Plasma was deproteinized with trichloroacetic acid and the supernatant was i...
