Abstract

The applicability of polyphenyl ether sulfone liquid phases for the separation of moderately “polar” materials, at temperatures of 200–400°, has been evaluated. A variety of samples was separated and typical chromatograms are presented for the resolution of a synthetic lubricant, long-chain alcohol derivatives, triglycerides, cholesteryl esters, bile acid esters, and pesticides.

In order to extend the utility of sulfone phases to temperatures below their melting points, columns were prepared with a porous thermally stable polymer as the support. The results obtained indicate that these columns are useful for the separation of wide-boiling mixtures of “polar” materials.

Pentafluorobenzoic anhydride as a derivatizing agent for alcohols and hydroxy fatty acid methyl esters detected by electron capture in gas chromatography
1989, Journal of Chromatography A
Pentafluorobenzoate derivatives of primary and secondary alcohols have been prepared using pentafluorobenzoic anhydride. The gas chromatographic properties of the homologous series of the methyl esters of 2-hydroxycarboxylic acids from C₁₂ to C₂₆ have been studied on the high-temperature stationary phase Poly-S 179. The suitability of determining trace amounts of these compounds using gas chromatography with an electron-capture detector and with electron-capture negative-ion chemical-ionization mass spectrometry is discussed.
Chapter 3. Gas chromatography
1984, New Comprehensive Biochemistry
This chapter discusses the role of contemporary gas chromatography (GC) in biochemistry. The ionization detectors used in GC possess unparalleled measurement sensitivity, and are the major reason for using GC in biochemical and biomedical investigations. The flame ionization detector has been extremely useful as a sensitive, universal detector, and there are numerous analytical problems where detection selectivity is required. A mass spectrometer employed in a mass-fragmentographic mode provides almost the ultimate in both selectivity and high sensitivity. The use of other selective devices, such as the electron capture, thermionic or flame-photometric detectors, has been steadily on the increase. Some of these detectors were primarily developed to overcome the problems of sample complexity, and an increasing use of capillary GC does not appear to diminish their importance. On the contrary, the columns of greater resolving power and higher degree of inertness further expand the utility of such detectors. The most frequent use of selective detectors in biochemical analysis is associated with the formation of derivatives that are particularly suitable for such detection.
Steroids
1983, Journal of Chromatography Library
This chapter focuses on high performance liquid chromatography (HPCL) of steroids and on natural products, including steroids available. It presents genuine sterols having one oxygen function. The genuine sterols and, especially, their esters are difficult to separate, because this class of steroids includes homologs (C₂₆ to C₃₀) and stereoisomers (C-3, C-5, and C-24 isomers). It also includes double-bond isomers, and the 24, 28-double bond may exhibit geometric isomerism, but the 22, 23-double bond usually has the trans-configuration. For the separation of free sterols by gas chromatography (GC), the phenylmethylsilicones, OV-17 and OV-25, are more suitable than the less polar stationary phases, UCCW-982 and SE-30. The relative retention times (RRT) of homologous sterols are in the order C₂₇ < C₂₈ < C₂₉. The effect of double bonds depends on the location in the molecule. Whereas conversion of sterols to their acetyl derivatives increases the RRT on all four of the stationary phases, conversion to the TMS ethers increases RRT in UCCW-982 and SE-30 but decreases them in OV-17 and OV-25 columns.

Polarity of a poly(oxy aryl sulfonyl arylene) used as a stationary phase in gas-liquid chromatography
Retention indices of polynuclear hydrocarbons, phenols and aza-arenes on poly(oxy aryl sulfonyl arylene) were measured at different temperatures. Comparison between these data and the retention indices of the same compounds on SE-30, polyphenylether (6 rings), OV-17, Carbowax 20M, shows the polarity of this stationary phase (PS 179) to be similar to that of Carbowax 20M.
The large polarity and the thermal stability of PS 179 permits the analysis of complex mixtures of heavy aromatic hydrocarbons and related compounds.
L'indice de retention de composés analysés par chromatographie sur PS 179 [poly(oxy aryl sulfonyl arylène)] dépend du support utilisé.
Parmi les supports étudiés nous avons choisi le Chromosorb W AW HMDS pour déterminer les indices de rétention d'hydrocarbures aromatiques polycycliques (2 à 5 noyaux) non fonctionnels et fonctionnels (hydroxylés, azotés).
La comparaison de ces indices avec ceux mesurés sur SE-30, polyphenyl ether 6 noyaux, OV-17, Carbowax 20M montre que la polarité du PS 179 est supérieure à celle du SE-30, du polyphenyl ether 6 noyaux et de l'OV-17 et voisine de celle du Carbowax 20M.
La polarité et la stabilité thermique du PS 179 permettent l'analyse de dérivés de masse moléculaire élevée des hydrocarbures aromatiques.
