Sorbent technology

Biotage, Uppsala, Sweden [International Sorbent Technology, Ltd., Glamorgan, UK]... [Pg.30]

Generally, SPE consists of four steps (Figure 2.42) column preparation, or prewash, sample loading (retention or sorption), column postwash, and sample desorption (elution or desorption), although some of the recent advances in sorbent technology reduce or eliminate column preparation procedures. The prewash step is used to condition the stationary phase if necessary, and the optional column postwash is used to remove undesirable contaminants. Usually, the compounds of interest are retained on the sorbent while interferences are washed away. Analytes are recovered via an elution solvent. [Pg.108]

The last decade has seen a tremendous improvement in HPLC instrumentation. However, the most significant changes have occurred in the column sorbent technology, detection, and automation. HPLC has become the primary tool in the pharmaceutical industry in characterizing the purity and impurities of pharmaceutical products. [Pg.97]

The reader should refer to chapters within the Handbook of Thin-Layer Chromatography [27] for a more thorough discussion of sorbents technology. [Pg.292]

Bond Elut (Agilent) and CBA ISOLUTE (International Sorbent technology) both representing an irregular end-capped mixed-mode phase of a weak cation exchanger (carboxylic acid) and a mid-polarity sorbent. /V-butyl-scopolamine was extracted accordingly from equine urine [78], Elution of analytes was achieved by the use of a methanolic solution acidified either with 1 M HC1 [54] or 1 % formic acid [78] allowing competition between QTA and hydronium ions. Recoveries were between 96 and 103 % [54] (Table 4). [Pg.311]
