20110000853 | PROCESS AND DEVICE FOR SEPARATING FRACTIONS OF A MIXTURE - The invention concerns a method for separating fractions of a mixture using a chromatography device. The method includes the following steps: controlling in one node of the device, the history of a specific variable of the fractions of the mixture to be separated; detecting one characteristic point of the history, the characteristic point being between two successive steps of fraction collecting; comparing the position of the characteristic point relative to a target position; adjusting the amount of mobile phase modifying the position of the characteristic point to cause the position of the characteristic point to coincide with the target position. The invention also concerns a device for implementing the method. The method enables the operation of the device to be automatically set. | 01-06-2011 |
20100163490 | MODULAR CHROMATOGRAPHY DEVICE - The subject of the invention is a chromatography device comprising: (i) a unit column intended to receive a chromatographic bed, (ii) a removable reservoir for a bed slurry, and (iii) a base comprising a cylinder adapted to a piston, said piston sliding in the removable reservoir and the column to compress the slurry of solid particles into a chromatographic bed; the column, reservoir and base being connected in series in this order, the piston acting to compress the slurry of solid particles into a chromatographic bed in the column. | 07-01-2010 |
20100012584 | METHOD FOR ENRICHING ONE OR MORE COMPOUNDS OF A MIXTURE USING A LIQUID MOBILE PHASE CONTAINING A GAS - The object of the invention is a method for enriching by chromatography of one or more compounds of a mixture in at least one column using an eluent, characterized in that a liquid mobile phase containing dissolved gas is used as eluent. A further object of the invention in the use in preparative chromatography of an eluent composed of a liquid mobile phase containing a dissolved gas. | 01-21-2010 |
