MRM parameters used for colistin A, colistin B and fusidic acid assays

Compound MRM (m/z) DP (V) CE (V) CXP (V)
Colistin A 585.4/241 156 29 12
Colistin B 578.7/227.2 151 29 22
Fusidic acid 515.3/221.0 −130 −36 −10

DP is the declustering potential, CE is the collision energy and CXP is the collision cell exit potential.
