摘要： A method of combining ES (ElectroSpray Ionization) and MALDI (Matrix Assisted Laser Desorption Ionization) to create enhanced MALDI mass spectrometry to be referred to as ESMALDI (ElectroSpray Matrix Assisted Laser Desorption Ionization). ESMALDI technology offers substantial advantages over conventional technology. essentially by combining the high ionization efficiency and multiple charging of ions in ESI with the smaller sample requirements and operational simplicity of MALDI. Biologists should thus be able to achieve higher sensitivity, better protein identification, enhanced quantification potential and enhanced structural information. An additional degree of freedom for ESMALDI MS is flexibility in the choice of solvents that can be used in the ESI component of the process. Substantial differences in ESI behavior can occur with the same analyte or mixture of analytes in different solvents. Such differences often provide clues to the properties of the analyte and its ions which cannot be readily obtained from conventional MALDI experiments.

摘要： A method of changing the energy of charged particles contained in a gas comprises allowing the gas to flow into a region of reduced pressure through a tube like member so that viscous forces exerted on the charged particles by the flowing gas molecules determine the kinetic energy of the charged particles. A potential gradient is maintained along the length of the tube so that the potential energy of the charged particles is changed as they pass through the tube. At the end of the tube a free jet expansion occurs so that the kinetic energy of the charged particles is no longer determined by the flowing gas, so that they can be accelerated to any desired kinetic energy by means of another potential gradient.The invention can be used to interface any high pressure ion source to a magnetic sector mass spectrometer, or to permit the operation of an electrospray ion source with an earthed inlet capillary with either a quadrupole or a magnetic sector mass spectrometer.

摘要： An electrospray mass spectrometric method for analyzing an aqueous solution containing inorganic ion species first enhances the signals for small inorganic ions in electrospray mass spectrometric analysis of aqueous solutions by substantially diluting a sample of the aqueous solution with an organic solvent. The method also removes solvent molecules and other ligands from the small inorganic ions formed in electrospray ionization before mass analysis is complete, by appropriate application of electric fields to accelerate the ions so they will have energetic collisions with neutral gas molecules.

摘要： The subject invention teaches the use of mechanical vibration to enhance the electrostatic dispersion of sample solutions into the small, highly charged droplets that can produce ions of solute species for mass spectrometric analysis. Such vibration turns out to be surprisingly effective at ultrasonic frequencies for solutions with flow rates, conductivities and surface tensions too high for stable dispersion by electrostatic forces alone as in conventional electrospray ionization. Several embodiments of the invention are described for purposes of illustration. Other possible embodiments will become apparent to those skilled in the art.

摘要： An electrospray ion source for a mass spectrometer capable of generating ions from samples dissolved in a solution comprises a capillary tube through which the said solution is pumped into a first chamber maintained substantially at atmospheric pressure and in which an inert gas is flowing in a direction counter to the flow of the solution, and a small orifice in the end wall of the chamber opposite to and aligned with the capillary. A high potential difference is applied between the capillary and the end wall so that the solution is electrosprayed into the chamber and ions characteristic of the sample are formed. These ions are desolvated to a controllable extent by the inert gas, which may also be heated to improve the efficiency of the process and increase the maximum permissible flow rate of solution. The ions so formed pass through the small orifice into a second chamber maintained at a reduced pressure, and into a mass spectrometer. Alternatively an additional pressure reduction stage can be included, so that the ions pass into a third chamber maintained at a still lower pressure in which the mass spectrometer is situated through a conventional nozzle and skimmer arrangement. The ion source is particularly effective for the production of unfragmented and unsolvated ions from thermally unstable or involatile samples, and may be used as a liquid chromatograph--mass spectrometer interface.
