The iEESI-MS source. (a) Schematic diagram of iEESI-MS: Signals of the interior analytes were captured when the solvent was delivered from an infusion pump at a flow rate 0.5 μL·min−1 and supplied with a high voltage +4.5 kV. (b) Cross-sectional drawing of the iEESI-MS source. (c) Physical map source of iEESI-MS. HV is high voltage.
