The Electronic Laboratory Notebooks in the laboratory information management system are electronic laboratory notebooks defined for laboratory users. Used to record information that is not captured in electronic form and unformatted information. Through the application of ELN, all inspection steps in the standard operating procedures are recorded in electronic worksheet form to ensure the standardization of each step and the original records. At the same time, all electronic record sheets are automatically merged into original inspection record files and inspection reports, thereby achieving the digitization and paperless processing of complex unformatted data in inspection records.
