Electronic Lab Notebooks ELN
The paper-based laboratory notebook is still widely used, and the way chemical research data is documented has hardly changed for a century. The progress of information technology in the laboratory (Smartlab) involves more than just tablets and touchscreens. It is about networking the entire workflow and handling research data according to the FAIR principles.
Electronic lab notebooks (ELNs) enable researchers to enrich experiments with extensive metadata and make the collected data traceable and reusable. The direct transfer of measuring devices to the ELN makes it the central repository for all data, which can then be easily published in repositories and transferred to long-term archives.
A key difference between ELNs and paper is the structured documentation of metadata that humans and machines can read. You can find further differences between simple systems, ELNs and laboratory information management systems (LIMS) in the knowledge base.

Advantages of an ELN
- ELNs link test descriptions directly to the collected data so that all information is available in one place.
- Secure data storage and backups prevent data loss.
- Centralised storage facilitates knowledge management and access to data, including for new members of a research project.
- The biggest advantage of an ELN is the structured and standardised storage of metadata, which facilitates the publication of research results and the transfer of data to repositories.
