Effect of ligand chain length on hydrophobic charge induction chromatography revealed by molecular dynamics

Lin ZHANG, Yan SUN

Frontiers of Chemical Science and Engineering 2013, Volume 7, Issue 4,   Pages 456-463 doi: 10.1007/s11705-013-1357-y

Abstract: Hydrophobic charge induction chromatography (HCIC) is a mixed-mode chromatography which is advantageousfor high adsorption capacity and facile elution.The adsorption, desorption, and conformational transition of the proteins with CL2 and CL4 were examinedligand chain length has a significant effect on both the probability and the irreversibility of the adsorptionLonger ligands reduced the energy barrier of adsorption, leading to stronger and more irreversible adsorption

Determination of persistent organic pollutants by gas chromatography/laser multiphoton ionization/time-of-flight

Frontiers of Environmental Science & Engineering 2012, Volume 6, Issue 1,   Pages 26-31 doi: 10.1007/s11783-011-0374-7

Abstract: An authentic mixture of polychlorinated biphenyls was measured using a short wide-bore capillary column for the group separation of major components present in an actual sample of Kanechlor. The limits of detection were improved by ca. 2 fold in comparison with those obtained using a conventional capillary column, since the retention time was reduced and the amount of analytes introduced into the mass spectrometer per unit time could be increased. On the other hand, surface-water and sediment samples containing polycyclic aromatic hydrocarbons (PAHs) were collected from the river located in the vicinity of a waste water treatment plant. Even acenaphthylene, a minor component of the mixture could be measured for the sediment sample, and the concentrations were determined for several heavy PAHs. As demonstrated, a technique involving laser multiphoton ionization/time-of-flight mass spectrometry was useful as a sensitive and selective analytical tool for the trace analysis of persistent organic pollutants in an environmental sample.
