Polyoxyethylene-based non-ionic surfactants resulting from the condensation of ethylene oxide with fatty alcohol cuts have been widely studied by high-performance liquid chromatography. Even though satisfactory analyses are obtained in normal-phase p

Previous work involved the utilization of the transalkylation reaction (retro-Friedel-Crafts reaction to transfer alkyl-substituting chains from the asphaltenes aromatic matrix to a light aromatic acceptor) in the analysis of heavy crude oil fraction

Seven new chiral stationary phases obtained from ( S )-phenylalanine derivatives, ( R )-Mosher's acid and ( S )-naproxen were prepared and evaluated. The racemic substances used to test them contained either π-acidic or π-basic sites. The best resu

A strategy for the overall analysis of pyrolysis oils is decribed based on the combination of a previously developed fractionation, the improved API 60 fractionation, with high-performance analytical techniques used in series, such as size-exclusion

Up to now, most stationary phase have had either π-acceptor or π-donor characteristics. In this study, the behaviour of stationary phases having mixed characteristics (π-donor and π-acceptor) was investigated and compared with that of silicas bon

We report the use of the transalkylation reaction (i.e. transfer of alkyl chains from the aromatic matrix to a light aromatic acceptor) as a tool for the analysis of different types of asphaltenes (Boscan, Arabian Light, Kirkouk, Maya and Duri). Beca

The performance of capillary supercritical-fluid chromatography (SFC) applied to the analysis of various polysiloxanes was compared with that of low mass size-exclusion chromatography (SEC). SFC gave far better results than SEC and appeared well adap
