Mestrelab Mbook (User Manual)

Significance of the topic

Mbook is a modern Electronic Laboratory Notebook (ELN) that centralizes the planning, execution, documentation and reporting of chemical experiments. It supports traceability, reproducibility and compliance with regulatory standards by combining reaction design, inventory control, safety assessments and analytical workflows in a single platform.

Objectives and Overview

This manual presents Mbook 3.1, whose main goals are:

• Define user hierarchies (Administrator, Group Manager, Project Manager, Bench Chemist, Guest) with tailored access.
• Enable efficient creation and management of groups, projects, reactions and experiments.
• Integrate reagent databases, spectroscopic data, COSHH risk assessments and inventory management.
• Automate reporting and data exchange, including XML/SDF export and customizable PDF generation.
• Provide an optional analytical module to handle instrument definitions, service offerings and client requests.

Methodology and Instrumentation

Mbook operates in any modern web browser and uses:

• An internal chemical structure database with an integrated sketcher (Marvin JS) and ChemDraw interoperability.
• A stoichiometric table that auto-calculates masses, volumes and equivalents.
• Attachment of raw/processed spectra (NMR, MS, ElViS) with Mnova integration for preview, processing and signature verification.
• A relational back end for inventory tracking (stockroom hierarchy, bottle consumption) and safety metadata (hazards, CMR categories, COSHH forms).
• User-managed templates for report headers and footers, supporting corporate branding and signature workflows.

Key Results and Discussion

The manual demonstrates:

• Flexible risk-based access control through roles and privileges, including witnessing and supervisory approvals of experiments.
• Granular inventory management linked to experimental sources, with real-time updates of bottle stock and purity adjustments.
• Automated stoichiometric column configuration at group, project or experiment levels.
• Export/import facilities for entire projects, reactions and experiments in ZIP archives containing XML, SDF and original attachments.
• An analytical extension that defines instruments by type/technique, configures client service offerings, and manages request lifecycles from sample submission to results approval.
• Structure verification via the Mbook Verify module, combining global spectral deconvolution, chemical shift prediction and matching thresholds to flag potential mismatches.

Contributions and Practical Applications

Mbook’s unified environment delivers tangible benefits:

• End-to-end digital record keeping for synthetic and analytical chemistry in one system.
• Enhanced collaboration via cloning experiments, in-app messaging and project notifications.
• Improved safety and compliance through mandatory COSHH sign-off and structured approval chains.
• Reduced manual errors with auto-calculated stoichiometry and interactive source assignment.
• Accelerated service-oriented analytics, enabling CRO-style workflows with client portals, instrument scheduling and result validation.

Future Trends and Opportunities

Potential avenues for Mbook development include:

• AI-powered reaction and spectral prediction to assist experimental design.
• Seamless integration with external LIMS, ELNs and public chemical repositories.
• Expanded machine-learning models for de novo structure elucidation from spectral data.
• Enhanced mobile and voice-activated data capture for lab-floor convenience.
• Open RESTful APIs to support custom dashboards and enterprise analytics.

Conclusion

Mbook 3.1 offers a comprehensive, flexible and secure ELN solution that bridges synthetic and analytical workflows. By unifying reaction planning, data capture, inventory control, safety compliance and reporting, it meets the complexity and collaborative demands of modern chemical research and quality management.
