Abstract
A sprayer assembly for an ion source is disclosed. The sprayer includes a capillary having an outlet, a sheath for the capillary, and an elastic member. The sheath can move relative to the capillary between a first position in which the sheath covers the outlet of the capillary and a second position in which the outlet of the capillary is exposed. When the sheath moves from the first position to or towards the second position, the elastic member provides a restoring force that acts to restore the position of the sheath to or towards the first position.
