摘要: The present invention relates to a method for controlling fraction collection of a target product 27 in a chromatography system 49 configured for cyclic purification performed on a sample comprising the target product 27. The method comprises determining trigger points for target product 27 collection in relation to presence of target product in the outlet; setting a first time period based on the trigger points within which the elution in the first cycle is captured; evaluating timing of the captured elution to identify the next time period; applying the timing to capture elution during the elution phase in the following cycle; and collecting the captured elution in the following cycle. The last three steps are repeated to capture the elution during the elution phase of the following cycles until no more target product 27 is desired.

摘要: The present invention relates to a preparative chromatography system (200, 500, 800) and a chromatography process (400, 700) adapted to repetitive cycling of chromatography volumes. The system (200, 500, 800) comprises at least two upstream pumps (203a, 803a, 203b, 803b) and separate flow paths (220) from process liquid sources to the chromatography device (200, 500, 800). The system (200, 500, 800) is arranged to prime one flow path (220) with one process liquid while providing another process liquid to the chromatography device and thereby minimizing the hold-up volume of the system (200, 500, 800).

摘要: A chromatography system for at least one of tangential flow chromatography and lateral flow chromatography comprising: an inlet; a functionalised adsorbent chromatography medium downstream of the inlet; an outlet downstream of the adsorbent chromatography medium; and a flow guide downstream of the inlet and upstream of the adsorbent chromatography medium and configured to distribute a flow of a liquid from the inlet across a width of the adsorbent chromatography medium; wherein the flow guide comprises a pattern of channels providing flow paths from the inlet to different parts of the adsorbent chromatography medium along the width of the adsorbent chromatography medium, wherein the pattern of channels is provided so as to reduce a difference in arrival time and/or flow velocity of liquid reaching the adsorbent chromatography medium across the width of the adsorbent chromatography medium.
