Axiomatization Decision Log
1
Identity-Giving Function
Function class
ChromatographicAnalysisFunction
⊑ DesignedFunction
Realized in
ChromatographicAnalysisProcess
⊑ MeasurementProcess
The identity-giving function is chromatographic analysis - the separation and analysis of molecular constituents using chromatographic principles. This distinguishes chromatographs from other analytical instruments that use different measurement principles (spectroscopy, electrochemical, etc.).
2
Genus Determination
Instrument
Both ISO 15926 and CFIHOS define chromatograph as a subtype of process analyzer/analysing instrument. This is the most specific appropriate superclass - chromatographs are specialized analytical instruments designed for process monitoring and composition analysis, not general-purpose laboratory instruments.
3
Necessary Parts
No necessary parts recorded (concept may be primitive at this level).
These four components define the essential chromatographic system architecture - sample introduction, mobile phase transport, selective separation, and component detection.
4
Process Participation Signature ⟨I, O, T⟩
Inputs (I)
PortionOfFluid
— representative sample from process stream
CarrierFluid
— inert mobile phase (gas or liquid)
Outputs (O)
CompositionMeasurementResult
— time-resolved detector response
CompositionMeasurementResult
— molecular constituent concentrations
Transformation (T)
physical separation of molecular constituents followed by detection and quantification
Chromatographs transform chemical sample inputs into analytical data outputs through the characteristic separation-detection sequence that defines chromatographic analysis.
5
Axiom Mode Decision
Necessary + Sufficient
— modelled as a defined class
(≡, EquivalentClass). Automatic classification is
appropriate for this concept.
Disjointness Axioms
Densitometer
C4: Densitometer. Incompatible analytical signatures - chromatographs require physical separation processes while other analyzers use electromagnetic, gravitometric, or electrochemical measurement principles without separation.
Cross-Standard Observations
Both ISO 15926 and CFIHOS definitions are consistent, emphasizing the chromatographic principle and molecular composition analysis. ISO 15926 provides more detailed hierarchical context with specific chromatography subtypes and detector specifications.
