Graphical diagram of the sample preparation workflow for ecdysteroid analysis. The detailed conditions are shown for the preparation of 1 μl of insect hemolymph. The sample preparation protocol includes three main steps: (a) extraction from biological material; (b) derivatization of the main ecdysteroid <t>20-hydroxyecdysone</t> <t>(20E)</t> with hydroxylamine; and PT-SPE purification with final MRM HPLC-MS/MS analysis on a triple quadrupole MS. The experimental conditions and MRM transitions for the 20E-oxime derivative are shown. PT-SPE, pipette tip solid-phase extraction; MRM, multiple reaction monitoring.
