Table 2.

Optimized mass parameters for sivelestat, XW-IMP-A and the internal standards.

Analyte MRM (m/z) Dwell time (ms) DP (V) CE (eV) EP (V) CXP (V)
Sivelestat 435.1→360.0 100 50 22 10 11
XWCl 469.0→394.0 100 50 22 10 11
XW-IMP-A 351.0→276.0 100 50 22 10 11
XWCl-A 384.9→310.0 100 50 22 10 11

Note: DP: declustering potential, CE: collision energy, EP: entrance potential, CXP: collision cell exit potential, ms: millisecond.
