System and method for the automation of column and media packing
View Patent ↗This invention provides for the fully automated, hands free, packing of chromatography columns by means of delivering a pre-calculated volume of slurry and using two different packing modalities to stop the packing when either 1) this volume has been delivered in the column, or 2) when the adapter is moved to reach a bed height corresponding to the pre-calculated volume. Thus, a chromatography column can be packed in a fully automated fashion and such a column is 1) stable and 2) has the desired performance characteristic.
1. A method for automating column packing comprising:
determining a slurry concentration for a slurry of a chromatography medium;
determining a column volume in a chromatography column;
determining a compression factor for the chromatography medium in the chromatography column;
calculating a volume of the slurry needed for packing the column with the determined compression factor, said calculation being based on the determined column volume, the determined compression factor and the determined slurry concentration;
configuring the calculated volume of the slurry in a slurry tank;
positioning the chromatography column for delivery and packing of the calculated volume of the slurry to the chromatography column;
monitoring the delivery of the calculated volume of the slurry to the chromatography column; and
automatically terminating the packing of the column by terminating the delivery of the slurry to the chromatography column when the volume of the slurry is equivalent to the calculated volume of slurry.
2. The method of claim 1 , wherein monitoring comprises:
providing a flow meter to read a value equal to the calculated volume of slurry.
3. The method of claim 1 , further comprising:
applying liquid to the chromatography column.
