More Information
Summary:The present invention relates to a method for monitoring operational status in a column capture chromatography system configured for cyclical repetitive purification performed on a volume of sample feed comprising at least one product configured to be captured in the column during loading. The method comprises: performing (51) a purification cycle; measuring (52) at least one parameter during the purification cycle indicative of breakthrough of the at least one captured product after the column during loading of sample feed; when breakthrough is detected, reducing (56a) the amount of sample feed loaded during loading in the next purification cycle; and repeating the steps to perform another purification cycle. Each purification cycle comprising: loading an amount of sample feed onto the column, washing the column and eluting the at least one product.
