The final stage, often referred to as polishing, is dedicated to removing any remaining trace impurities and achieving the precise quality standards required for the final product. This is particularly critical for high-value products like pharmaceuticals, where minimal contamination is essential for safety and efficacy. Highly selective techniques, such as size-exclusion chromatography or further passes of affinity chromatography, are typically used. For biologics, viral inactivation or removal steps are often integrated here. The process may conclude with formulation, where the purified product is combined with excipients to improve stability, solubility, or delivery, possibly involving steps like lyophilization (freeze-drying).

Common Downstream Processing Techniques

A variety of techniques are employed in downstream processing, each leveraging different principles to achieve separation and purification. The selection of appropriate methods depends heavily on the nature of the product, the impurities present, and the desired final specifications. Companies across the United States utilize these techniques to meet diverse industrial needs.

Chromatography

Membrane Filtration

Membrane filtration employs semi-permeable membranes to separate components based on size or molecular weight.

Nanofiltration can remove divalent ions and smaller molecular weight impurities while retaining larger product molecules. Microfiltration is used for removing cells or large particulates.

Crystallization and Precipitation

These techniques exploit differences in solubility. Crystallization is frequently used for small molecule drugs and certain industrial compounds as a final purification step, yielding highly pure solid forms. Precise control over solvent conditions, temperature, and supersaturation is necessary. Precipitation methods, such as adjusting pH to the isoelectric point or adding salts (salting out), can selectively cause the product or impurities to aggregate, allowing for their removal by filtration or centrifugation.

Cell Disruption and Solid-Liquid Separation

For products produced intracellularly, effective cell disruption is the first hurdle. Techniques include high-pressure homogenization, bead milling, or enzymatic treatment. Following disruption, solid-liquid separation is essential to remove cell debris. Centrifugation, using various types of industrial centrifuges, and filtration are the primary methods employed at this stage.
