An improved ionization source (1) for use with any atmospheric pressure inlet (71) mass spectrometry system (7) is provided herein. The improved ionization source 1 comprises an electrode (2) having a deposition area (21) or a capillary channel (22) for introducing a sample, or an electrode (2) having a capillary channel (23) for introducing a solvent (or solvent mixture) while the sample is positioned in between (24) the ionization source (1) and the atmospheric pressure inlet (71) of the mass spectrometry system (7), and a power supply (3) having an output (32) coupled to the electrode and a USB-compatible input (31) and further comprising a controllable transformer (33) to transform an input supply voltage (Vs) provided at the USB-compatible input (31) into a high voltage (VH) at the power supply output, and a controller (34) for controlling the controllable transformer (33). The improved ionization source (1) is widely applicable as it can be directly coupled to any mobile device (5) having a USB-port. Moreover, control tasks can be performed by the mobile device (5) in response to user input, remote control and/or an autonomously operating application program functionalities.
