    摘要: Improved apparatuses and methods are provided for ionizing samples and analyzing the samples with mass spectrometry. A liquid sample is electrosprayed into droplets out of the delivery end of a capillary. A conduit surrounds the capillary for transmitting a heated gas, the conduit being connected to a nozzle to release the heated gas into the ionization chamber, wherein the nozzle comprises at least one electrode to which a potential can be applied, which contributes to the generation of an electrical field at the delivery end of the capillary.

    摘要: An ion source is disclosed for forming multiply-charged analyte ions from a solid sample (110). A beam of pulsed radiation (12o) is directed onto a portion of the sample to desorb analyte molecules, A retaining structure (135) holding a solvent volume (130) is positioned proximate the sample. Desorbed analyte molecules contact a free surface (210) of the solvent and pass into solution. The solution is then conveyed through an outlet passageway (140) to an electrospray apparatus (145, 235), which introduces a spray of charged solvent droplets into an ionization chamber.

    摘要: An improvement to Desorption Electrospray Ionization (DESI), the process of creating ions directly from sample surfaces for mass spectrometric (MS) analysis by impinging a liquid spray onto the surface. The improvement is brought about by enclosing the spray and sample surface and MS-inlet capillary in a pressure tight enclosure. The invention includes methods of sampling a larger or smaller area of surface by impacting and collecting droplets from such an area. The invention allows DESI to be performed without need for careful control of the geometry of the sprayer and MS-inlet capillary positions and angles relative to the sample surface.
