User-defined attributes in HPLC injections

It’s possible to add your own user-defined properties to Injections:

  • Either do this manually using the menu next to injection name

  • Or use the programmatic API and SDK to submit a JSON with properties

This can be useful if you want to store external information (like reaction conditions), which will later be available in visualizations & reports, as well as over the API.

There are limitations both on the number of properties and the total size of the properties JSON.
When creating a property via UI, its type (number or a string) is determined automatically. In rare cases it’s possible that the type is determined incorrectly. Using the API to define the props will guarantee the correct type.

Batch-level visualizations & reports

You can use the custom properties when building visualizations and reports. Such properties will be named as-is, so don’t name them similarly to the standard attributes so as not to confuse others.

Raw Metadata properties

The properties that are coming directly from the raw files are stored similarly, see Injection Metadata props.
