New support for the affinity chromatography of hemoglobin.
J. Chromatogr. B. Biomed. Sci. Appl. 694(1) , 39-48, (1997) A new support for affinity chromatography of hemoglobin was synthesised from EAH Sepharose-4B containing a hexamethylamine spacer. Benzenetetracarboxylic (BTC) or benzenehexacarboxylic (BHC) acids were covalently bound to the spacer arm. At pH close to the pI... |

Pyrones to pyrans: enantioselective radical additions to acyloxy pyrones.
J. Am. Chem. Soc. 128(41) , 13346-7, (2006) This paper describes a highly site-, diastereo-, and enantioselective intermolecular radical addition/hydrogen atom transfer to hydroxypyrone pyromeconic and kojic acids. The methodology can be extended to the formation of chiral quaternary centers. The produ... |

Modification and validation of the pyromellitic acid electrolyte for the capillary electrophoretic determination of anions.
J. Chromatogr. A. 995(1-2) , 217-26, (2003) For the determination of inorganic and organic anions, the pyromellitic acid (PMA) electrolyte is widely used. The pH adjustment of the self-prepared electrolyte was very challenging to satisfy the pH of specification of pH 7.8 +/- 0.1. A modification was pro... |

Ion-exclusion chromatography of carboxylic acids on silica gel modified with aluminium.
J. Chromatogr. A. 850(1-2) , 177-85, (1999) The modification of silica gel with aluminium by a coating method was effective for the preparation of a silica-based stationary phase, which acted as a cation exchanger under strongly acidic conditions. In order to expand the utility of the laboratory-made a... |

Relationship between chromatographic properties of aromatic carboxylic acids and their structure.
J. Chromatogr. A. 948(1-2) , 65-7, (2002) The retention of aromatic carboxylic acids and their esters in reversed-phase HPLC is proportional to the sum of their partition coefficients in octanol-water system and retention increments. This equation can be used for the identification of various side-pr... |
