Parallel Chromatography Column Assembly for Uniform Residence Time

The patent merges multiple chromatography columns into a single integrated parallel assembly housed within one rigid housing structure. The columns are arranged adjacently and connected to common fluid manifolds, combining what would traditionally be separate column installations into one unified system. This merging approach maintains the capacity and flexibility benefits of parallel configuration while reducing the overall footprint by eliminating gaps and redundant support structures between individual columns.

The patent implements a nested arrangement where multiple chromatography columns are positioned closely together within a compact rigid housing, with fluid manifolds routed through the interstitial spaces between columns. This nesting strategy allows the columns to be packed more efficiently in three-dimensional space, maximizing the use of available volume while minimizing the external footprint of the overall system.

The patent employs universal, standardized chromatography column modules that can be used in various configurations (parallel, series, or individual operation) within the same system. These standardized modules share common specifications for fittings, connections, and dimensions, allowing them to serve multiple functions and be interchangeably deployed. This universality reduces the overall cost by eliminating the need for custom-designed columns for each application and enabling economies of scale in manufacturing and inventory management.

The patent segments the chromatography system into modular, standardized column units that can be independently manufactured, tested, and assembled. Each module is designed as a discrete, replaceable component with standardized interfaces, allowing the system to be built by assembling multiple identical or similar units. This segmentation approach reduces cost by simplifying manufacturing processes, enabling parallel production of modules, and reducing the need for expensive custom engineering for each column.

The patent combines multiple chromatography columns into a single rigid housing structure that provides unified mechanical support for all columns. The housing acts as a common framework that distributes and shares the mechanical loads and pressure stresses across all columns, rather than each column needing to independently withstand full system pressures. This merging of structural support reduces the individual rigidity requirements of each column while maintaining overall system strength.

The patent introduces a rigid housing and common fluid manifolds as intermediary structures that mediate between the individual chromatography columns and the external environment. These intermediary components absorb and distribute mechanical stresses, providing a stable structural framework that protects the columns from pressure fluctuations and mechanical shocks. The manifolds act as pressure equalization chambers that reduce peak pressure loads on individual column connections.

The patent merges the fluid distribution function into a simplified manifold system that is integrated directly into the rigid housing structure. Rather than using separate, complex external manifolds, the housing itself incorporates channels and ports that distribute fluid to all columns. This merging of the housing structure with the manifold function eliminates the need for additional complex piping and connection hardware, reducing installation complexity while maintaining scalability.

The patent designs the rigid housing with built-in fluid distribution channels that automatically route process fluid to all column inlets and collect effluent from all outlets. The housing structure itself performs the manifold function, eliminating the need for separate manifold components. This self-service approach reduces complexity by having the primary housing structure provide multiple functions (structural support, fluid distribution, and column mounting) without requiring additional specialized components.
