Abstract
The Waters ACQUITY UPLC I-Class/Xevo TQD IVD System enables the quantification of organic compounds in human biological liquid matrices.
This document describes a test of the analytical performance of the ACQUITY UPLC I-Class/Xevo TQD IVD System for the analysis of citalopram, desmethylfluoxetine, duloxetine, fluoxetine, fluvoxamine, O-desmethylvenlafaxine, mirtazapine, sertraline, trazodone, and venlafaxine in plasma.
Experimental
The ACQUITY UPLC I-Class/Xevo TQD IVD System was controlled by MassLynx™ Software (v4.2) and the data processed using the TargetLynx™ XS Application Manager. Calibrators and Quality Controls were prepared by spiking commercially available reference material in plasma and the samples were processed using the following conditions:
Sample Preparation Conditions
A 50 µL sample was processed with acetonitrile and centrifuged, then subsequently diluted with water prior to analysis.

Results and Discussion
Chromatographic selectivity of a range of antidepressants using the ACQUITY UPLC I-Class/Xevo TQD IVD System is illustrated in Figure 1. Performance characteristics of the antidepressant drugs are shown in Table 1.
Table 1. Performance characteristics of the analytes evaluated. *Calibration Range was defined by linear fit where r2 >0.995 for O-Desmethylvenlafaxine and duloxetine; for all other analytes a quadratic fit was used. LLOQ defined by S/N (PtP) >10 with %RSD ≤20% and ≤15% bias (with the exception of fluoxetine, for which bias was 17.6%). %RSD at LLOQ determined through analytical sensitivity experiments performed over five occasions (n=50). Total precision and repeatability of QCs performed over five occasions in plasma (n=25).

Conclusion
The Waters ACQUITY UPLC I-Class/Xevo TQD IVD System has demonstrated the capability to analyze a panel of antidepressant drugs in plasma.
