1. Column Hardware Mechanical Description: Evolve™ Process Columns are designed specifically for use in biopharmaceutical applications and can be used in both pilot and production scale chromatographic processes. A pressure rating of 4 bar, operating temperature range of 2-30°C and adjustable bed height makes this column suitable for a wide range of chromatography media types and chromatographic techniques.
Pressure Drop The pipework and column contribute to the pressure drop of the chromatographic system. Measuring the pressure drop from the column inlet to the column outlet shows the contribution made by the column hardware. The tests were performed at ambient temperature 15-20°C using RO water.
Material Conformity All materials in contact with the process stream have been selected for their suitability for use in equipment utilised in biopharmaceutical applications and so either conform to relevant sections of FDA code of Federal Regulations vol. 21 170-199 and/or have passed USP class VI test for in vivo toxicity.
Chemical Compatibility Acrylic columns are ideally suited for aqueous-based applications. See the table below for detailed compatibility information. Key: Resistant; suitable for continuous use Not resistant; not recommended Resistance Limited resistance No information available All solvents are at 100% concentration unless noted otherwise Notes General Concentrations: % refer to w/w...

3. Column Installation and Operation Column Installation The column is shipped pre-assembled. On receipt, it is recommended to check for damage or loosening of components during transit. Complete instructions for disassembly and reassembly can be found in the ‘Maintenance’ section of this operating manual. The following column preparation and installation procedures should be followed prior to operation: Install of bed supports and flow path checks Leveling the column...
Figure 5 Photograph showing the installation of the fixed bed support 3. Locate fixed flow cell into the tube unit and fix in place. (3) Levelling the Evolve™ Process Columns After installation of the fixed flow cell and before installation of the adjuster unit, it is recommended to level the column.
Work around the circumference of the flow cell ensuring that seal is correctly fitted. See Figure 7. Figure 7 Photograph showing the location of the adjuster bed support (5) Setting the Bed Height Reinstate the adjuster unit in the acrylic tube, using the location pins and ensure the adjuster seal is de-energized.
4. Column Operation This section provides general guidance on operating the Evolve™ range of columns. It includes a hydrostatic leak test to establish that the column is installed correctly and advice for the preparation of the chromatography media. Further advice specific to each chromatography media should be attained directly from the media manufacturers guide;...
Column Packing (Constant Flow Rate Method) 1. To identify the column components, see the schematics in this subsection. 2. Attach a valve to the fixed end pipe spool. 3. Remove the adjuster assembly. 4. Fill the fixed cell with buffer until approximately 20 mm depth of buffer is seen in the acrylic column tube.

19. If the media is compressible, the packed bed may expand while the adjuster is being lowered, and it may prove necessary to repeat steps 16 to 18 above. 20. When the final bed height has been reached, turn the seal actuation knob to apply maximum seal compression.
Unpacking The column may be unpacked conventionally, that is, the adjuster can be removed, the bed re- slurried and the media poured or pumped out of the acrylic column tube. Cleaning The extensive solvent and chemical resistance of the column components allows the use of a wide range of Cleaning and sanitization solutions, including: •...
5. Maintenance Routine Maintenance Procedures and General Guidelines To disassemble and reassemble the Evolve™ Process Columns follow the instructions below. Note: after reassembling the Evolve™ Process Column ensure that the column does not leak by performing a hydrostatic leakage test. When assembling/dissembling attention should be paid to: CAUTION! Column units are heavy and can roll 1.
Disassembly of Evolve™ Process Columns Adjuster Assembly 1. Detach any pipework from the top sanitary clamp adapter. 2. Remove flange fixing bolts from the underside of the top tube flange. 3. Check that adjuster seal is released by turning the seal actuation nut counterclockwise. 4.
Fixed Assembly 1. Disconnect the pipework elbow from the bottom of the column. 2. Using the fixed end fixing tool and torque wrench, loosen each of the fixing screws, supporting the flow cell with your hand. Remove the flow cell and place it on a clean work surface. 3.
Reassembly of Evolve™ Process Columns Note: Reassembly of the column is the reverse of disassembly. Fixed Assembly 1. Install the process flow tube into the back of the flow cell. Ensure the flow tube seal is located. Tighten process flow tube using correct tools. 2.
4. Support the flow cell with your hand and locate fixing bolts. Initially, hand tighten the bolts, working diametrically opposite to ensure equal loading on the seal. Then using the fixed end fixing tool and torque wrench, tighten the bolts to the torque settings shown in the table below. Column Model Torque Setting Torque Setting Ft lbf...

Note: alignment pins are located in the top flange to assist orientation. CAUTION - Adjuster units are heavy 10.Locate the flange fixing bolts in the underside of the column tube flange and tighten.
6. Troubleshooting Note: Refer to the ‘Maintenance’ section before undertaking any procedure advised below. Leakage from Adjuster Seal • Ensure that the adjuster seal is not damaged or twisted. If the seal is damaged, replace. • Ensure no media or other foreign material is trapped between the seal and sealing faces on the acrylic column tube, flow cell and seal setting ring.
• Unpack and empty the column. Run a pressure drop test over a range of flow rates and compare results to pressure/flow curves in this manual. • Ensure all connections to/from the column are correctly connected and correct size pipework and ladish seals have been used. •...

9. Chromatography Performance To determine chromatographic efficiency of a packed chromatography column it is usual practice to inject a small analytical sample onto the column and monitor the response at the outlet. Typical solutions used are acetone in RO water or a 1.0 M NaCl solution. If acetone solution is used, then the UV absorbance is measured and plotted.

Two further calculations can be performed to describe column efficiency. Reduced plate height - takes into account the particle size of the media and enables comparison between different media types. A low value of RPH denotes good column efficiency; a RPH of less than 6 is expected.
