A sensor in Chemolytic represents a physical spectrometer in your lab. Every spectrum you upload is linked to the sensor that produced it. This matters for three reasons:
  • Reproducibility: models are trained on spectra from a specific instrument. Linking each spectrum to its sensor means you always know exactly what hardware produced your training data.
  • Traceability: when a prediction is made months or years later, you can trace it back to the instrument, its configuration, and the original calibration data.
  • Resilience over time: if an instrument is replaced or recalibrated, you can register the new sensor separately, retrain, and compare models side by side without losing historical data.

Sensors page

Go to Sensors in the project sidebar to see all sensors registered in the project.
Sensors page showing a table with sensor name, type badge, manufacturer and model, units, and predefined status
Each sensor shows: You can search sensors by name and sort by: newest, oldest, name A-Z, or name Z-A.
Your plan limits how many sensors you can add per project. The current count and limit appear at the top of the page.

Sensor detail

Click any sensor row to open the detail panel.
Sensor detail side panel showing name, type, manufacturer, units, creation info, and x-axis range
The detail panel shows:
  • Created by and Created date
  • Predefined: whether the sensor came from the catalog
  • Points: number of data points per spectrum (appears after the first spectrum is uploaded)
  • Range: actual min and max x-axis values detected in uploaded spectra (appears after first upload)
  • Custom fields: any metadata you added (serial number, location, firmware version, etc.)

​
X-axis setup

When you upload the first spectrum for a sensor, Chemolytic reads the x-axis values from that file and locks them as the sensor’s calibration template. All subsequent spectra uploaded to that sensor must have the same number of points and the same x-axis range. This is automatic and not user-editable. It ensures all spectra from the same sensor are directly comparable.
Once the first spectrum is uploaded, the x-axis is locked. If you need a different x-axis (e.g., different resolution or range), create a new sensor.

​
Editing a sensor

In the detail panel, scroll to the Edit section. You can update the Name and Description. All other fields (type, units, model) are set at creation and cannot be changed. Click Save changes when done.

​
Deleting a sensor

You can only delete a sensor that has no spectra linked to it. Delete or archive all associated spectra first, then return here to remove the sensor.
In the detail panel, scroll to the danger zone and click Delete. A confirmation dialog appears before anything is removed. Only users with the Contributor role or higher can delete sensors.
