The Pluto system was recently explored by NASA's New Horizons spacecraft, making closest approach on 14 July 2015. Pluto's surface displays diverse landforms, terrain ages, albedos, colors, and composition gradients. Evidence is found for a water-ice

Silicalite as a stationary phase for HPLC

Autor: Philip J. Dumont, James S. Fritz

Publikováno v: Journal of High Resolution Chromatography. 19:691-695

A molecular sieve known as Silicalite was used as the column packing for HPLC. Silicalite contains channels (or cavities) approximately 6 A in diameter but, unlike most other molecular sieves, Silicalite is hydrophobic. The retention times of methyl

Cation-exchange chromatography in non-aqueous solvents

Autor: James S. Fritz, Luther W. Schmidt, Philip J. Dumont

Publikováno v: Journal of Chromatography A. 706:109-114

Much of the selectivity of organic ions in conventional ion chromatography comes from hydrophobic interaction between the carbon chain of the analyte ions and the polymer matrix of the ion exchanger. By operating in organic solvents containing little

Ion chromatographic separation of alkali metals in organic solvents

Autor: Philip J. Dumont, James S. Fritz

Publikováno v: Journal of Chromatography A. 706:149-158

Ion-exchange chromatography is a common method for the separation and determination of metal cations. Although much research has been done on improving various aspects of this technique, the use of non-aqueous eluents has received little attention. T

Methods and materials for solid-phase extraction

Autor: Luther W. Schmidt, James S. Fritz, Philip J. Dumont

Publikováno v: Journal of Chromatography A. 691:133-140

Solid-phase extraction (SPE) with porous solid particles goes back to the early 1970s. However, SPE has become more popular recently due to the availability of more efficient particles and the need to replace liquid extraction procedures that require

Effect of resin sulfonation on the retention of polar organic compounds in solid-phase extraction

Autor: Philip J. Dumont, James S. Fritz

Publikováno v: Journal of Chromatography A. 691:123-131

The hydrophobic nature of polymeric resins used in solid-phase extraction (SPE) often limits their efficiency by preventing intimate surface contact with aqueous samples. A polymeric resin modified by a series of chemical derivatizations with sulfuri
