  • Automatic chromatography process
    Patent number: 4861488
    Abstract: Automatic chromatography apparatus comprises a column packed with adsorbent or attractant material;means for supplying an elutant solution to the column;loading means for loading controlled quantitites of a material into the column, the material containing a substance to be eluted;automatic control means which control the loading means so as to load the column with a first charge of the material and subsequently to load the column with a second charge of the material, the first charge being sufficiently small to ensure that the capacity of the column is not exceeded and the second charge being sufficiently large to ensure that the capacity of the column is exceeded;first monitoring means for monitoring and controlling flow rate to provide accurate flow information to enable peak area integration;second monitoring means which monitor the peaks of elution of the substance from the column resulting from the first and second charges of material;processing means connected to the monitoring means and arranged to in
