Definition

planned process during which dissolved, entrained, or adsorbed gas is separated from a liquid or solid material

Explanatory Notes

Degassing process separates material commonly described as dissolved, entrained, or adsorbed gas from a liquid or solid material. In this context, dissolved gas does not imply that the material is in a gaseous aggregate state while dissolved; for example, dissolved dioxygen molecule in culture medium is molecular material present in a liquid solution. Entrained gas may be present as gas bubbles, while adsorbed gas may be associated with a solid surface or solid material

Examples

• vacuum degassing of culture medium prior to sterilization; nitrogen sparging to remove dissolved oxygen from buffer solution

Synonyms

• degasification process

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

DegassingProcess(x) → PlannedProcess(x) ∧ ∃m ∃q ∃g ∃gq (MaterialEntity(m) ∧ hasInput(x, m) ∧ hasSpecifiedOutput(x, m) ∧ ((LiquidAggregateState(q) ∨ SolidAggregateState(q)) ∧ hasQuality(m, q)) ∧ MaterialEntity(g) ∧ hasOutput(x, g) ∧ GaseousAggregateState(gq) ∧ hasQuality(g, gq))

Semi-Formal Natural Language Axioms

if x is a ‘degassing process’ then x is a ‘planned process’ that ‘has input’ some ‘material entity’ that ‘has quality’ some ‘liquid aggregate state’ or some ‘solid aggregate state’, that same ‘material entity’ is also the ‘specified output’ of x, and x ‘has output’ some ‘material entity’ that ‘has quality’ some ‘gaseous aggregate state’
