ABSTRACT:
A probe for supporting a sample in an ion source of a mass spectrometer comprises a target formed by a copper probe tip for a liquid sample in which the sample passes through a fine bore 18a of the tip on to the end surface of the tip where it is held as a droplet by surface tension. In order to replenish the droplet surface, capillary tubing leads from a syringe to the inlet end of the bore in the probe tip.
