Consistent Packing Performance for Diverse Media Types with QuikScale Biochromatography Columns TM The scalable family of QuikScale columns delivers faster linear velocities. greater product purity at The design of the QuikScale column is uniquely robust, enabling the column to be used over a broad range of conditions in a variety of processing environments. This technical brief will illustrate that the QuikScale column performs well over a wide range of temperatures and flow ranges. The QuikScale columns contain stainless steel Porostar® bed supports and can operate with both soft gels and fast high-performance media for MAb purification. Flow tube kits are offered for QuikScale columns that are geared specifically for high throughput processing. The QuikScale column’s patent-pending liquid seals ensure operational integrity for reliable process handling. The consistent performance of the QuikScale column simplifies the validation efforts necessary to qualify the separation process as well as reducing manufacturing operating costs and processing time. Excellent Performance over a Wide Range of Temperatures QuikScale columns are designed for use over a broad range of environmental conditions from 2 °C to 35 °C. Under changing environmental conditions, dissimilar column materials expand and contract, often at divergent rates, potentially leading to seal and/or material failure. Moreover, the mechanical strengths of materials change as a function of temperature, thereby imposing additional design considerations in order to maintain safe and predictable column operation. The QuikScale column has been engineered to minimize the effects of changing environmental conditions. A 100 mm QuikScale column was hydrostatically tested to 7 bar at the boundaries of the recommended operational temperatures. The test was conducted statically at nominal temperatures of 2 °C, 20 °C, and 35 °C for extended periods of time. Figure 1 shows the equipment used for the ambient testing.

0.4 Maximum Allowable Pressure Decay (15 minute interval) 0-3 o D | 0.2- Figure 2 illustrates the pressure decay exhibited at maximum operating pressure across the recommended operating temperature range. The 100 mm QuikScale column held 7 bar of hydrostatic pressure at temperatures spanning the recommended operating range. Excellent Performance over a Wide Range of Linear Velocities The QuikScale column family has been designed to minimize flow resistance throughout the column while maintaining consistent performance across the operating range. The capacity to operate reproducibly at high...

The pressure differential across all QuikScale columns was very low in all configurations tested. Additionally, the enhancement in linearity achieved with the optional larger diameter flow tube kits results in greater flexibility during process development. Figure 4 illustrates the pressure flow curves for the QuikScale columns. Summary The robust design of the QuikScale column allows it to operate effectively over a wide range of temperatures and linear velocities. QuikScale columns will work well for virtually all process development and production scale applications in a wide variety of...
