Giebelhaus Lab @ UVic

Resources and Tools

A collection of online resources we have developed for processing metabolomics data. These are all open source and free to use. See the publications section for the appropriate publication. Feel free to contact Dr. Giebelhaus if you are having difficulties deploying or using any of these resources and tools. Please cite all work when appropriate.

Normalize to Total Derivitized Peak Area: MATLAB code developed for using mass spectra to compute total derivitized peak area in a sample for GC based metabolomics studies. totalDerivPeakNorm

Region of Interest Selection for GC×GC-MS data: MATLAB code for probability based ROI selection tool for GC×GC-MS data. Can be incorporated into any existing chemometrics workflow. ROI-Code-GC×GC-MS

HormonomicsDB: A free webtool developed for the putative identification of phytohormones and their conjugates in untargeted LC-MS datasets. Includes an option to query against a custom database. HormonomicsDB.com

Laboratory Equipment

Laboratory Space

Currently we are located in the basement of Petch in a temporary space. Stay tuned as we move to our permenant lab in 2026.

Sample Preparation

We have all sample preparation equipment and supplies for performing most LC-MS and GC-MS based metabolomics assays and methods. Additionally, we can develop new metabolomics methods.

Our sample preparation equipment includes pipettes (positive displacement and air aspirated), centrifuges, and a bead beater.

Analytical Instruments

Currently we have one HPLC-UV (donated by UVIC MS Facility) in our lab. We run quantification assays on this WATERS 2695 Alliance. We have a wide assortment of RPLC and HILIC columns. For MS analysis, we currently rely on the UVIC MS Facility and the UVIC Proteomics Centre.
