Test data is inconsistent
Taking the test data from http://purl.allotrope.org/test/adm/liquid-chromatography/REC/2021/12/liquid-chromatography.json and using your Jupyter notebook.
The chromatogram has retention time in seconds, with the chromatogram of only 30 seconds in length and 3 visible peaks.
The peak table lists them with > 360 s retention time, which is out of bounds.
identifier | peak start.value | peak start.unit | retention time.value | retention time.unit |
---|---|---|---|---|
f1382e45-159e-4eb1-bd6e-6b004fd08289 | 363.049994 | s | 367.214527 | s |
6a9ce7f0-cf16-4d90-afbc-aea5854264ca | 372.309179 | s | 372.750235 | s |

I suspect the original chromatogram was actually measured in minutes.
