Abstract
The invention generally relates to ion generation using modified wetted porous materials. In certain aspects, the invention generally relates to systems and methods for ion generation using a wetted porous substrate that substantially prevents diffusion of sample into the substrate. In other aspects, the invention generally relate to ion generation using a wetted porous material and a drying agent. In other aspects, the invention generally relates to ion generation using a modified wetted porous substrate in which at least a portion of the porous substrate includes a material that modifies an interaction between a sample and the substrate.
Claims10
A system, the system comprising:
- a porous substrate comprising a tip;
- a mass spectrometer that comprises an inlet;
- a cartridge configured to hold at least a portion of the porous substrate within a body of the cartridge, and an electrode operably coupled to the porous substrate within the body of the cartridge such that when the porous substrate is disposed within the cartridge, the electrode is operably coupled to the porous substrate;
- wherein the cartridge further comprises a distal opening configured to accommodate a distal portion of the porous substrate and the tip of the porous substrate and wherein the cartridge is aligned with the inlet of the mass spectrometer such that the tip of the porous substrate aligns with the inlet.
