Applicable Classes
| Name | Description | Modifies Slot |
|---|---|---|
| ProductIdentificationMethod | Abstract Plan representing the method used to identify and quantify reaction products. In practice, users should reference a concrete CharacterizationTechnique subclass from coremeta4cat_characterization_ap (e.g. GCMS, HPLC_MS, NMRSpectroscopy). This abstract class is retained for backward compatibility with the original CoreMeta4Cat monolith. It is a subclass of Plan (prov:Plan / OBI:0000272) so that it can participate in the realized_plan slot if needed. |
