| titleOfInvention | Improved process for analyzing, for separating, and for isolating individual polar protic monomers and/or oligomers |
| abstract | A process for separating and isolating individual polar protic monomer(s) and/or oligomer(s) on the basis of degree of polymerization is disclosed. A liquid sample containing monomer(s) and/or oligomer(s) is introduced into a liquid chromatography (LC) column packed with a polar bonded stationary chromatographic phase. The individual monomer(s) and/or oligomer(s) are separated via a binary mobile phase elution. The monomer(s) and/or oligomer(s) may be proanthocyanidins, hydrolyzable tannins, oligosaccharides, oligonucleotides, peptides, acrylamides, polysorbates, polyketides, poloxamers, polyethylene glycols, polyoxyethylene alcohols, or polyvinyl alcohols. The binary mobile phase comprises an A phase consisting essentially of a polar aprotic solvent and a B phase consisting essentially of a polar protic solvent. A process for separating and isolating xanthine(s) e.g., caffeine and theobromine is also disclosed. A liquid sample containing xanthine(s) and the monomer(s) and/or oligomer(s) is introduced into an LC column packed with a polar bonded stationary chromatographic phase. The xanthines are separated via an isocratic mobile phase elution and the individual fraction(s) are eluted. A process for separating and isolating the xanthines as well as polar protic monomer(s) and/or oligomer(s) is also disclosed. The phases discussed above are used in this rocess. |
