Moment analysis of chromatographic behavior of superficially porous particles.
Peak parking experiments were conducted to study the chromatographic behavior in a RPLC system consisting of a column packed with superficially porous C(18)-particles and a mixture of methanol and water (70/30, v/v). The values of the surface diffusion coefficient and the retention equilibrium constant of a column packed with superficially porous C(18)-particles were comparable to those of col...
متن کاملFast and Efficient HPLC Separations With Superficially Porous Particles
The current trend in liquid chromatography is towards the achievement of higher kinetic efficiency and shorter analysis time. Different types of column packings are now available for attaining very fast and high resolution separations without changing instruments, worrying about high backpressure or compromising column longevity. In recent developments of particle technology, the use of superfi...
متن کاملNucleic acid separations using superficially porous silica particles
Ion pair reverse-phase liquid chromatography has been widely employed for nucleic acid separations. A wide range of alternative stationary phases have been utilised in conjunction with ion pair reverse-phase chromatography, including totally porous particles, non-porous particles, macroporous particles and monolithic stationary phases. In this study we have utilised superficially porous silica ...
متن کاملEvaluation of 5 µm Superficially Porous Particles for Capillary and Microfluidic LC Columns.
Large-size (4-5 µm) superficially porous particles yield lower plate heights (e.g., the minimal reduced plate height or hmin ≈ 1.5) than fully porous particles of a similar size when packed into large-bore columns. This property allows for better chromatographic performance without the higher pressures required for smaller particles. This study explores the use of such particles in microfluidic...
متن کاملwoman-defined identity: analysis of selected poems of adrienne rich
the current thesis is composed in five chapters in the following fashion: chapter two encompasses the applied framework of the project in details; the methodology of carl gustav jung to explain the process of individuation, the major archetypes and their attributes and his techniques to assess the mind’s strata are all explained. moreover, the austrian psychoanalysts, heinz kohut’s models of a...
