Mass Spectrometry

Mass Spectrometry is considered the gold standard in drug and metabolite analysis, with the advantages being its ability to detect drugs/metabolites at very low concentrations, its ability to distinguish a specific drug/metabolite from all other compounds in a biologic sample, and its speed, meaning a short turnaround time for results.

The Mass Spec CORE is a shared resource of WSU Health Sciences in Spokane. We gratefully acknowledge the Health Sciences and Services Authority of Spokane County for their financial support.

Xevo® G2-S QTof

The instrument, Xevo® G2-S QTof, is designed for scientists who need to identify, quantify, and confirm the broadest range of compounds in the most complex and challenging samples. Incorporating StepWave™ ion optics for unsurpassed levels of durable sensitivity, the Xevo G2-S QTof also uses proven quantitative time-of-flight (QuanTof™) technology to deliver superior UPLC®-compatible mass resolution, matrix tolerant dynamic range, quantitative performance, mass accuracy, and speed of analysis – simultaneously.

Sciex 6500

The SCIEX 6500 Series with IonDrive™ technology merges highly evolved sensitivity with renowned performance. Adopting an intelligent approach to increasing limits of quantitation, the new patented IonDrive™ technology introduces a series of system-wide technological advances that not only increase the number of ions produced, but also enhances the way ions are transmitted and detected. This system is intended for the qualitative and quantitative analysis of chemical species.


Note: These rates are currently being evaluated and may increase as of July 1, 2020. Finalized rates will be announced soon. As a reminder, it is best practice to plan for a 3 to 5 percent yearly rate increase when proposing studies and submitting grants.
