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.

LC Conditions

Column:

XSelect™ Premier HSS T3, 2.5 µm, 2.1 mm x 100 mm

Mobile phase A:

2 mM ammonium acetate in water

Mobile phase B:

2 mM ammonium acetate in methanol

Flow rate:

0.4 mL/min / 0.6 mL/min

Gradient:

40% A initial, hold until 1.70 minutes, then ramp gradient 6 until 20% A at 4.00 minutes, at 4.01 minutes switch to 100% B at a flow rate of 0.6 mL/min until 4.50 minutes, finally return to 40% A at 0.4 mL/min from 4.50 until 5.0 minutes.

MS Conditions

Resolution:

MS1 (0.75 FWHM), MS2 (0.75FWHM)

Acquisition mode:

MRM

Polarity:

ESI+

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.
