MassHunter Quantitative Analysis Webinar Series - Quant-My-Way Unknowns Analysis

Significance of the Topic

Modern analytical laboratories require flexible software environments that can adapt to diverse instrumentation and workflows. The ability to tailor data-processing interfaces and efficiently identify both targeted and unknown compounds is critical for high‐throughput quantitation, trace-analysis screening and regulatory-compliant reporting. Agilent’s MassHunter Quant-My-Way customization and its Unknowns Analysis module provide a streamlined solution for these needs.

Objectives and Overview of the Presentation

This document summarizes two key capabilities of the MassHunter Quantitative Analysis B.09.00 platform:

• The Quant-My-Way feature for creating, managing and sharing custom interface layouts (“flavors”) to match individual lab preferences.
• The Unknowns Analysis workflow for deconvolution, library searching, component review and reporting of tentatively identified compounds in complex samples.

Methodology

The Quant-My-Way module allows users to:

• Install and configure predefined and custom desktop icons during setup.
• Create “flavors” by selecting toolbars, ribbons and menu items relevant to a specific instrument or operator style.
• Share flavors across workstations to maintain consistency.

The Unknowns Analysis workflow proceeds through:

• Batch import from a prior quantitative analysis (batch.bin or batch.xml).
• Peak detection using Total Ion Chromatogram integration, deconvolution or feature extraction algorithms.
• Library searching with configurable search criteria (normal, fast, forward/reverse scoring, retention time or accurate mass matching).
• Compound identification and target match for semi-quantitative estimates based on response factors.
• Blank subtraction with flexible retention time windows and threshold settings.
• Component review via interactive tables, chromatogram overlays, head-to-tail spectra and extracted-ion chromatograms.
• Report generation using a PDF Report Builder or customizable templates for targeted hit lists, screening summaries and QC documentation.

Main Findings and Discussion

The customization of user interfaces through Quant-My-Way:

• Reduces clutter by exposing only necessary commands and hiding advanced or unused features.
• Improves operator efficiency and minimizes training time when transitioning across different instruments.

In Unknowns Analysis:

• Deconvolution parameters such as retention-time window size factor and extraction window critically influence component grouping and sensitivity to co-elution.
• Library search modes offer trade-offs between speed and comprehensiveness, with fast indexed searches enabling real-time screening in high-throughput labs.
• Target match and semi-quantitation features leverage existing calibration data to provide rapid concentration estimates for unknowns without full quantitative workflows.
• The integration of filtering, spectrum comparison and interactive chromatogram tools facilitates confident assignment of tentatively identified compounds.

Benefits and Practical Applications of the Method

These capabilities enable laboratories to:

• Adopt a single software environment for both routine quantitation and non-target screening.
• Customize user interfaces to support specific application needs, from environmental screening to pharmaceutical impurity profiling.
• Generate regulatory-ready reports with minimal post-processing.
• Scale workflows across multiple instruments while maintaining data consistency.

Future Trends and Applications

Emerging developments may include:

• Integration of AI-driven spectral matching to improve unknown identification accuracy.
• Cloud-based sharing of flavors and lookup libraries to accelerate collaborative method development.
• Enhanced multi-omics deconvolution algorithms for combined LC–MS/MS and GC–MS workflows.
• Automated QC flagging and advanced dashboarding for real-time monitoring of screening performance.

Conclusion

Agilent MassHunter Quant-My-Way and the Unknowns Analysis module offer a flexible, user-centric approach to both targeted quantitation and non-target compound screening. Customizable layouts increase operator productivity, while the powerful deconvolution and library-search tools support rapid identification of unknowns. Together, these functions enable laboratories to meet evolving analytical challenges with a unified software platform.
