Publication number: 20140166557Abstract: A chromatography system may include: a first solvent supply operatively connected to a chromatography column; a second solvent supply operatively connected to the chromatography column; a controller operatively connected to the first and second solvent supplies for delivering a flow of a solvent system to an inlet for the chromatography column in accord with a predetermined solvent gradient, wherein the flow of the solvent system through the chromatography column will separate components from a sample composition; and a collection apparatus operatively connected to an outlet from the chromatography column for collecting designated portions of the solvent system flow exiting the column. The controller may determine a target sample mass as a function of chromatography column parameters.Type: ApplicationFiled: February 20, 2014Publication date: June 19, 2014Applicant: BIOTAGE ABInventors: Jeffrey A.

Patent number: 8679345Abstract: Provided are methods and apparatus for determining conditions for performing chromatography, particularly flash chromatography. The methods may be utilized for separating compounds in a sample in a column chromatography system. The method includes determining at least two retention factors corresponding to the TLC performance of a target compound and an adjacent compound and defining a sample loading amount and a solvent gradient profile using at least two solvents that will result in differential elution of the target and adjacent compounds from a chromatography column. The chromatography system and loading parameters may be selected to provide satisfactory separation of the target compound from adjacent compounds.Type: GrantFiled: March 1, 2010Date of Patent: March 25, 2014Assignee: Biotage ABInventors: Jeffrey A.
