Continuous Chromatography

Multi-Column Chromatography Solutions for Minimizing Costs

Biopharmaceutical manufacturers and CDMOs purifying mAbs are eager to simplify downstream operations. Traditional batch chromatography is more time-intensive and requires large amount of protein A resin. Multi-column chromatography (MCC) solutions, offer a number of advantages. For example, the first column in MCC has a greater binding capacity, reducing protein A resin requirements. And, with several columns operating in parallel, MCC enables manufacturers to explore continuous processing.

How to Select Your DSP Chromatography Technology

Making the switch from single batch to multi-column chromatography can dramatically reduce resin utilization, reducing costs and eliminating bottlenecks without sacrificing quality. This animated feature compares the traditional, single batch approach to a multi-column alternative for mAb capture.

Reduce resin usage by 80%

Continuous loading of the column and elimination of idle periods improve resin capacity utilization, reducing resin usage by 80%

Increase productivity by up to 3-5x

Run identical simultaneous separations, increasing productivity of the resin 3–5x while maintaining very high yields

Improve flexibility by allowing simultaneous operation on 1-8 columns

Operate between 1-8 columns (16 for process development) on a single system to accommodate a wide range of titers and future process configurations

Find the Right Multi-Column Chromatography Solution

The BioSMB platform is a fully scalable solution for your manufacturing environment and is supported by a global Field Application Services team with MCC experts who can provide installation support. BioSMB PD is designed for process development and small-scale manufacturing, while BioSMB Process systems are designed for clinical and commercial manufacturing. In the latter, there are two flow range variants available — BioSMB Process 80 and BioSMB Process 350. The two systems cover typical single-use perfusion and fed-batch bioreactor-based processes.

Traditional Batch vs. Multi-Column Chromatography

Continuous Multi-Column Chromatography: Better Than Batch Chromatography

In traditional single-column batch chromatography, there are inherent limitations because the system rarely uses the full capacity of the stationary phase during loading. In multi-column chromatography, the large column is split into a number of smaller columns that can be processed individually, eliminating idle zones. In addition, the flexible valve configuration allows breakthrough of the product stream to a secondary column, which allows the full capacity of the column to be used through overloading, leading to improved process efficiency with increased resin capacity utilization.

Batch Chromatography

  • Single large column
  • Loading stopped before the column is saturated
  • Idle bed volumes, leading to increased cycle time
  • Higher resin volume requirement for a given batch size and processing time
  • Large footprint due to stainless-steel columns and support infrastructure for single unit operation

Multi-Column Chromatography

  • Number of smaller columns  
  • Efficiency Gain 1: Controlled overloading of columns by capturing breakthrough on another column, thereby utilizing unused capacity
  • Efficiency Gain 2: Elimination of idle volumes of packed bed by dividing a larger column into smaller sections that can be processed independently and quickly
  • Efficiency gains lead to lower resin volume requirement, reducing resin usage by 80%
  • Small footprint, eliminating the need for packing skids and other support infrastructure
