  • Innovative cut-and-feed operation for enhancing the performance of ion-exchange chromatographic separation
    Patent number: 7976708
    Abstract: The present invention relates to a process of enriching element content in stable isotopes of light elements in ion-exchange chromatography. The process comprises development of band of light elements in a chromatographic column; elution of said band in a discontinuous basis so as to disconnect said chromatographic column at particular stage; and finally the process comprises of regeneration step.
