Abstract
A probe and method for using the same for supporting a sample in an ion source of a mass spectrometer comprises a target formed by a receptacle for a liquid sample in which the sample passes by diffusion to the high vacuum side of a semipermeable membrane and/or in which the sample is held as a droplet by surface tension. In order to replenish the droplet surface, the supply can be arranged to overflow the receptacle.
