Abstract
Integrated nanospray ionization package, comprising a nanospray emitter, a push button carriage with button element projecting through a bore in said package, an integral high voltage contact pin, a bore in said package for reversible protrusion of the nanospray emitter, a push-and-retract spring mechanism in which the range of forward motion of the emitter is not dependent on range of travel of the said button, and then upon actuation of said button element and spring element for retraction of said nanospray emitter, said nanospray emitter is pushed forward to establish electrical contact, and upon release of said button retracts and breaks the electrical contact.
