Connected Solutions for Metabolomic and Lipidomic Studies on the Xevo MRT Mass Spectrometer

Significance of the topic

Metabolomic and lipidomic profiling are essential tools to understand biochemical pathways, disease biomarkers, and drug metabolism. However, integrating data across diverse protocols and software platforms often limits confidence in identification and biological interpretation. The Xevo MRT mass spectrometer combined with dedicated informatics workflows addresses these challenges by unifying sample separation, high-resolution detection, and streamlined data handling to enhance reproducibility and depth of analysis.

Objectives and Study Overview

The primary goal is to demonstrate a fully integrated solution for untargeted and semi-targeted metabolomics and lipidomics using the Xevo MRT system. This overview covers the alignment of chromatographic chemistries, MS acquisition strategies (DDA, DIA), and informatic pipelines linking waters_connect and Mass Analytica software to deliver efficient statistical interpretation and structural annotation of analytes.

Methodology and Instrumentation

The workflow employs the ACQUITY Premier UPLC system coupled to the Xevo MRT QTof mass spectrometer, providing up to 100,000 resolution at 100 Hz with sub ppm mass accuracy. Data acquisition is managed via the waters_connect platform, where the embedded DATA Convert application generates mzML files in real time. This open file format ensures compatibility with both commercial (MARS, LipoStar2, MassMetaSite) and open-source tools (MS-DIAL, MZmine, XCMS). Acquisition modes include MS, MS/MS, DDA, and DIA, with options for centroid conversion and data compression.

Main Results and Discussion

Integration of hardware and software components significantly reduces time to result while maintaining exceptional data quality. Alignment of positive and negative ion mode data facilitates comprehensive lipid annotations. Fragmentation algorithms and stable isotope labeling enhance structural confidence. Multivariate statistical analysis within the linked informatics suite streamlines trend discovery and pathway mapping, accelerating biological interpretation.

Benefits and Practical Applications

• Seamless integration into existing pipelines via mzML or API
