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.

Abstract: A union for coupling two or more segments of tubing or optical fiber, having an elastomeric core with two or more tubular sections encased in a through bore of a union body, the ends of the union body bore having compression nuts having through bores for insertion of segments of tubing or optical fiber to be coupled, which, tubular sections, when compressed by the compression nuts, deform radially inwardly to hold and seal the segments of tubing or optical fiber inserted therein.

Abstract: Feedback control system for electrospray nozzle using optical system for monitoring and controlling dynamic or static morphology of the fluid exiting the electrospray nozzle.

Abstract: Method for loading a capillary channel with a packing material to form a capillary column which comprises placing a first frit on a first capillary channel, forcing a slurry of a solid packing material in a liquid through said first channel so that the liquid, but not the solid packing material, passes through the frit and out of the capillary channel, to form a first bed of packing material within said first capillary channel and adjacent to the frit; thereby forming a pre-pack column, then removing the frit and joining the pre-pack column to an empty second capillary channel and attaching a second frit to the end of said second channel, then forcing a liquid into the end of pre-pack column, so that the liquid passes through the pre-pack column, mobilizing the packing therein and carrying it into the second capillary channel, where the liquid, but not the packing material, passes through the frit and out of said second channel, whereby said packing forms a packed bed in the second column; then separating the
