General description
CHIROBIOTIC® T and T2 have teicoplanin as the chiral selector. They offer unique selectivity for a number of classes of molecules, specifically underivatized α, β, γ and cyclic amino acids, N-derivatized amino acids, hydroxy-carboxylic acids, acidic compounds including carboxylic acids and phenols, small peptides, neutral aromatic analytes and cyclic aromatic and aliphatic amines. Separations normally obtained on a chiral crown ether or ligand exchange-type CSPs are also possible on the CHIROBIOTIC® T and T2, but in much simpler mobile phases, like water-alcohol. In addition, all of the known beta-blockers (amino alcohols), and dihydrocoumarins have been resolved. CHIROBIOTIC® T and T2 differ in their bonding chemistry and the pore size of the support particle, giving them different selectivity and preparative capacity.

A stereoselective liquid chromatography-tandem mass spectrometry assay was developed and validated for quantification of S- and R-metoprolol at concentrations of 0.5-50 microg/L in human plasma. Metoprolol was extracted from plasma by liquid-liquid extraction with ethyl acetate (82% recovery). Chromatographic separation
