Chiral Separation Chromatography

The ULTRON ES series consists of columns designed specifically for chiral separations that employ chemically immobilized protein (ULTRON ES-OVM, ULTRON ES-PEPSIN, ULTRON ES-BSA) and cyclodextrin (ULTRON ES-CD, ULTRON ES-PhCD) stationary phases.

ULTRON ES-OVM / ULTRON ES-OVM-C / ULTRON ES-OVM-M

Features

  • Employs the protein ovomucoid as the stationary phase.
  • Enables separations of a wide variety of compounds ranging from basic to acidic.
  • Can be used for reversed-phase analyses.
  • Suitable for trace analyses.
  • Designed to confirm separations of Clopidogrel bisulfate (USP) [ULTRON ES-OVM-C]
  • Designed to confirm separations of Escitalopram oxalate (USP) [ULTRON ES-OVM-E]
  • Corresponded to L57

Comparison data between 5 μm and 3 μm

LC/MS analysis example

This column can be used for analyses for LC/MS employing volatile buffers such as ammonium acetate or ammonium formate.

Direct injection of a sample containing HSA

It is possible to separate optical isomers of Ketoprofen in HSA-containing samples even on direct injection of untreated samples without adverse effects due to HSA. In addition, as the ovomucoid stationary phase is a trypsin inhibitor, adverse effects due to samples containing trypsin are also kept to a minimum, making it suitable for analyses of biological samples.

ULTRON ES-OVM / ULTRON ES-OVM-C / ULTRON ES-OVM-E

ULTRON ES-PEPSIN

Features

  • Employs pepsin, which is a polypeptide-digesting enzyme of pig stomach mucous membrane origin as the stationary phase.
  • Effective for the enantiomer separation of amino alcohols such as β-blocker medicines.
  • Can be used for reversed-phase analyses.
  • Suitable for trace analyses.
