Chromatography reversed phase liquid

In liquid chromatography, reversed-phase materials such as Cig and Cg are the most commonly used sorbents (429, 430, 434, 438, 446, 447, 453, 454). Examples of baseline separations with reversed-phase columns of several groups of anabolics including stilbenes, resorcyclic acid lactones, and other, frequently used anabolics have been reported (463-466). In addition to reversed-phase separations normal-phase separations of anabolics using either Hypersil (467) and Brownlee (456) silica or diol-modified silica have been reported. Although not all analytes were completely separated, the latter column could be efficiently used to differentiate between estrogenic and androgenic compounds within a mixture of 15 anabolics and their metabolites (468). [Pg.1064]

S.6.4.2 Reversed-phase ion-pair liquid chromatography. Reversed-phase ion-pair chromatography is an alternative approach for controlling the retention of ionic compounds. This approach is particularly useful for the separation of amines on silica-based columns and it has had a profound effect on the analysis of this class of compounds. In particular, the combination of reversed-phase ion-pair liquid chromatography and electrochemical detection revolutionized the analysis of neurotransmitters in the brain (Tomlinson et al., 1978 and refs, therein). [Pg.62]

The mechanism of SPE is directly related to liquid chromatography toxins have to be retained by the adsorbent and not eluted by the water in the sample. Extraction sorbents are therefore similar to those used in liquid chromatography, reversed-phase ( -alkyl silica, apolar copolymers, graphitized carbon) for aqueous samples, or ion exchangers for charged compounds. Extraction parameters can be directly extrapolated from the retention times of the analytes as measured by liquid chromatography with water as the mobile phase. [Pg.5105]

C18 layers have been found to have clo,se correlation with HP liquid chromatography reversed-phase columns (Gonnet and Marichy, 1979), and TLC is used widely to scout appropriate mobile phases for HPLC (see Chapter 6). Very polar substances (basic and acidic pharmaceuticals) can be separated on RP layers by ion pair chromatography. [Pg.40]
