For basic functional group-containing pharmaceuticals, the complexation was driven by cation exchange and hydrophobic interactions depending on the properties of the interacting compounds.Keywords: binding, fluorescence spectroscopy, humic acid, ...
Pickering Laboratories specializes in the manufacturing of cation-exchange columns and eluants for amino acid analysis. Post-column derivatization with Ninhydrin offers unmatched selectivity and reproducibility of the analysis for most challenging matrixes. ...
Various layering structures (e.g., monolayer, bilayer, pseudo-trilayer and pseudo-quadrilayer) are observed in the gallery of organoclays, depending on the chain length of alkyl ammoniums and cationic exchangeable capacity of clays. In particular, the long alkyl chains do not lie flat within a single layer but interlace, and likely jump to the next layers. ...
