Introduction
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 vitamin A and vitamin E in serum.
Experimental
The ACQUITY UPLC I-Class/Xevo TQD IVD System was controlled by MassLynx IVD Software (v4.2) and the data was processed using the TargetLynx Application Manager. In-house calibrators and quality controls were prepared by spiking commercially available reference material in serum. The samples were processed using the following conditions:
Sample Preparation Conditions
A 100-μL sample was processed with ethanol and water and centrifuged. The supernatants were diluted then loaded onto Oasis PRiME HLB μElution plates, washed, and eluted prior to analysis.

Results and Discussion
Chromatograms illustrating the chromatographic selectivity of vitamins A and E are shown in Figures 1 and 2. Performance characteristics of vitamins A and E on the ACQUITY UPLC I-Class/Xevo TQD IVD System are shown in Table 1.
Conclusion
The Waters ACQUITY UPLC I-Class/Xevo TQD IVD System has demonstrated the capability to deliver analytically sensitive, accurate, and precise performance for vitamins A and E in serum.
