EXPERIMENTAL DETAILSThe ACQUITY UPLC I-Class/Xevo TQD IVD System was controlled by MassLynx™ IVD (v4.1) and the data processed using the TargetLynx™ Application Manager. Whole blood Calibrators and Quality Controls were processed using the following conditions:
Sample preparation conditions50 µL sample was processed with aqueous zinc sulphate, acetonitrile, and centrifuged. Each analyte was analyzed individually.
LC CONDITIONSColumn: ACQUITY UPLC HSS C18 SB
1.8 µm, 2.1 mm x 30 mm
Mobile phase A: 2 mM Ammonium acetate + 0.1% formic acid in water
Mobile phase B: 2 mM Ammonium acetate + 0.1% formic acid in methanol
Flow rate: 0.4 mL/min
Gradient: 50% B for 0.2 minutes, 50–100% B over 0.4 minutes, hold 100% B for 0.6 minutes, equilibrate with 50% B for 0.6 minutes at 0.6 mL/min

ACQUITY UPLC I-Class/Xevo TQD IVD System: Analytical Performance for Immunosuppressive Agents
INTRODUCTIONThe 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 cyclosporine, everolimus, sirolimus, and tacrolimus in whole blood.
MS conditionsResolution: MS1 (0.75 FWHM), MS2 (1.2 FWHM)
Acquisition mode: MRM
Polarity: ESI (+)
RESULTSPerformance characteristics of cyclosporine, everolimus, sirolimus, and tacrolimus on the ACQUITY UPLC I-Class/Xevo TQD IVD System are shown in Table 1. Analytical sensitivity of the system is illustrated in Figure 1.
