| Field | Value |
|-------|-------|
| Acronyme | CHMO |
| Description | CMO, the chemical methods ontology, describes methods used to<br><br>    collect data in chemical experiments, such as mass spectrometry and electron microscopy<br>    prepare and separate material for further analysis, such as sample ionisation, chromatography, and electrophoresis<br>    synthesise materials, such as epitaxy and continuous vapour deposition <br><br>It also describes the instruments used in these experiments, such as mass spectrometers and chromatography columns. It is intended to be complementary to the Ontology for Biomedical Investigations (OBI). |
