  • Method and apparatus for bioaffinity separation
    Patent number: 5004547
    Abstract: Bioaffinity separation is carried out in a cascade of column segments under control of a computer which selectively connects each column segment to a collector so that the individual bioactive components which are selectively retained by a biospecific sorbent can be individually collected. The volume and flow rate of eluate collected following each segment serve as the measure for the addition of makeup eluant between that column segment of the cascade and the next column segment.
