Accelerated Solvent Extraction: A Technique for Sample Preparation
Bruce E. Richter,Brian A. Jones,and John L. Ezzell,Nathan L. Porter,Nebojsa Avdalovic and,Christopher A. Pohl +5 more
TL;DR: In this paper, the authors describe a new technique for sample preparation, accelerated solvent extraction (ASE), that combines elevated temperatures and pressures with liquid solvents, and investigate the effects of various operational parameters (i.e., temperature, pressure, and volume of solvent used) on the performance of ASE.
Journal ArticleDOI
Enantiomeric recognition of organic ammonium salts by chiral crown ethers based on the pyridino-18-crown-6 structure
Richard B. Davidson,Jerald S. Bradshaw,Brian A. Jones,N. K. Dalley,James J. Christensen,Reed M. Izatt,Frederick G. Morin,David M. Grant +7 more
TL;DR: In this paper, enaniomeric recognition by one chiral host for a pair of chiral guests is correlated with X-ray crystallographic data for the same system using three chiral dimethyl diester pyridino-18-crown-6 ligands.

Accelerated solvent extraction method
Bruce E. Richter,Christopher A. Pohl,Nathan L. Porter,Brian A. Jones,John L. Ezzell,Nebojsha Avdalovic +5 more
TL;DR: In this paper, an organic solvent system is used to extract analytes under elevated temperatures and pressures above 100 psi but below supercritical conditions in short times and with low amounts of solvent, the extracted organic analytes are then removed by flowing a purge fluid through the extraction cell, the cell being maintained at a constant volume throughout the extraction and purging, afterwards the analytes being analyzed.
Journal ArticleDOI
Synthesis of smectic liquid-crystalline polysiloxanes from biphenylcarboxylate esters and their use as stationary phases for high-resolution gas chromatography
TL;DR: Synthese de huit nouveaux composes cristaux liquides a base de l'ester (hydroxy-4 phenyl)-4 benzoate as mentioned in this paper.
Journal ArticleDOI
Polarizable polysiloxane stationary phases for capillary column gas chromatography
Milton L. Lee,J. C. Kuei,Adams Nathan William,Bryon J. Tarbet,Masaharu Nishioka,Brian A. Jones,Jerald S. Bradshaw +6 more
TL;DR: In this article, a biphenyl polysiloxane was synthesized and evaluated for capillary column gas chromatography, and the results showed that the polarizable phases demonstrated better selectivity in a number of isomer separations.
