Patent number: 11460454Abstract: A method for monitoring, evaluating and controlling a cyclic chromatographic purification process that involves at least two adsorbers. According to the method, one step is monitoring of the chromatogram, including the measurement of at least one current concentration-proportional signal in the liquid. Another step is conducting an evaluation of the chromatogram, including a comparison of at least one of the current concentration-proportional signals measured in the monitoring step with a threshold value thereof. A further step is controlling the chromatographic purification process by adapting the termination of the currently running phase as a function of the comparison of the evaluation step and initiating the next phase. Finally, according to the method, the sequence of steps is carried out in given order at least twice.Type: GrantFiled: November 6, 2018Date of Patent: October 4, 2022Assignee: ChromaCon AGInventors: Lars Aumann, Thomas Müller-Späth, Michael Bavand

Patent number: 11180526Abstract: A cyclic chromatographic purification method for the isolation of a product from a feed mixture consisting of the product and at least one further component representing impurities, which impurities bind stronger to the chromatographic stationary phase than the product is given. The method uses at least two chromatographic adsorbers as chromatographic stationary phase, grouped into only one first adsorber section (1) and one second adsorber section (2), wherein if an adsorber section comprises more than one chromatographic adsorber these are permanently connected in series, wherein the first adsorber section (1) has a first adsorber section inlet and a first adsorber section outlet, and the second adsorber section (1) has a second adsorber section inlet and a second adsorber section outlet.Type: GrantFiled: July 10, 2017Date of Patent: November 23, 2021Assignee: ChromaCon AGInventors: Thomas Müller-Späth, Lars Aumann, Michael Bavand

Patent number: 10099156Abstract: A chromatographic purification method for the isolation of a desired product fraction from a mixture using 2 chromatographic columns, comprises, within one cycle to be carried out at least once, the following steps: a first batch step, wherein said columns are disconnected and a first column is loaded with feed and its outlet is directed to waste, and from a second column desired product is recovered and subsequently the second column is regenerated; a first interconnected step, wherein the outlet of the first column is connected to the inlet of the second column, the first column is loaded beyond its dynamic breakthrough capacity with feed, and the outlet of the second column is directed to waste, a second batch step analogous to the first batch step but with exchanged columns; and a second interconnected step, analogous to the first interconnected step but with exchanged columns.Type: GrantFiled: January 31, 2014Date of Patent: October 16, 2018Assignee: ChromaCon AGInventors: Thomas Müller-Späth, Lars Aumann, Guido Strohlein, Michael Bavand, Nicole Ulmer

Patent number: 9073970Abstract: A chromatographic process for the enrichment of at least one compound of interest from a mixture is proposed, using chromatographic columns, wherein said process involves a sequence of the following steps: (i) a cyclic accumulation phase, in which the chromatographic columns are alternatingly operated in an interconnected phase, followed by a disconnected phase, wherein subsequently columns exchange places and wherein the phases are carried out sequentially; (ii) a cyclic separation phase, in which the chromatographic columns are alternatingly operated in an interconnected phase, followed by a disconnected phase, wherein after these phases columns exchange places to undergo the next interconnected and disconnected phases; and (iii) an elution phase, in which from the column, which at the end of phase (i) or at the end of phase (ii) contains the compound of interest, is extracted via the outlet.Type: GrantFiled: January 29, 2014Date of Patent: July 7, 2015Assignee: ChromaCon AGInventors: Thomas Müller-Späth, Guido Ströhlein, Lars Aumann, Michael Bavand, Nicole Ulmer
