Definition
viral clearance during which viral particles are physically separated from the input material based on differences in physical properties such as size or charge
Examples
- anion exchange chromatography operated in flow-through mode to remove retrovirus-like particles from CHO cell harvest;nanofiltration of plasma-derived products to remove non-enveloped viruses; use of tangential flow filtration to separate viral particles from cell lysate during vaccine production

Primitive Class
This class is declared primitive and it does not have necessary and sufficient condiftions defined.
Primitive Rationale
Insufficient constructs are present to create a set of necessary and sufficient conditions
Formal Axioms
First-Order Logic Axioms
ViralRemovalProcess(x) → ViralClearance(x)
Semi-Formal Natural Language Axioms
if x is a ‘viral removal process’ then x is a ‘viral clearance’
