Next-Generation Stationary Phases: Properties and Performance of Core–Shell Columns
September 1st 2012This short review focuses on the physicochemical properties of core–shell particles and their resulting chromatographic efficiencies as they relate to the comparison of their mass transfer kinetics to those of columns packed with sub-2-?m fully porous particles.
Ultratrace Quantitive Analaysis of Catalyst Poisoners Using a Dedicated GC–MS Analyser
September 1st 2012A dedicated GC– MS analyser was developed to address the increasing need for more sensitive catalyst poisoner analysis. The system combines the separation power and robustness of a classic backflush configuration with the selectivity and sensisitivitiy of mass spectrometry.
