In this paper, the preparation and performance of long, high-efficiency poly(styrene-divinylbenzene) (PS-DVB), 10-microm-i.d. porous layer open tubular (PLOT) capillary columns are described. PLOT capillaries ( approximately 3% RSD column-to-column retention time), with relatively high permeability, were prepared by in-situ polymerization. Relatively high(More)
The redox properties and thiol reactivity of quinones play critical roles in their therapeutic and toxicological properties. The present study was undertaken to investigate the binding activity of ubiquinone 0 (UQ(0)) to human oxyhemoglobin (HbO(2)) using electron spin resonance (ESR). Addition of UQ(0) to HbO(2) resulted in the immediate detection of a(More)
Following on our recent work, on-line one-dimensional (1D) and two-dimensional (2D) porous layer open tubular/liquid chromatography-electrospray ionization-mass spectrometry (PLOT/LC-ESI-MS) platforms using 3.2 mx10 microm i.d. poly(styrene-divinylbenzene) (PS-DVB) PLOT columns have been developed to provide robust, high-performance, and ultrasensitive(More)
