Abstract:
A new electrospray emitter capable of cone-jet mode spray for liquid flow-rates from sub-microliter/minute to 10's of microliters/minute is provided. The high efficiency of ionization and vaporization enabled by the disclosed spray emitter provides improved sensitivity for mass spectrometer detection. The disclosed spray emitter sprays consistently and robustly a liquid buffer having a large range of compositions of aqueous and organic solvents, and is not sensitive to the polarity of the electric field used to induce spray. The fluidic channel leading to the spray emitter opening does not have an internal taper rendering the spray emitter clog-resistant.

Claim (Index 18):
The spray emitter of  claim 17 , wherein the sample deposition area has an increased surface roughness, the trough having a raised middle area to divide the trough into first and second concave trough sections, the trough being defined by outer edges that are disposed above a top of the raised middle area so as to permit the fluid to be contained within the trough so as to cover the raised middle area; and\n the electrical conducting device disposed being configured to form on the raised middle area a liquid tip of a spray when the sufficient electric field is applied to electrical conductive device.
