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.
Claims20
A method for analyzing a sample, the method comprising:
- providing a cartridge configured to hold at least a portion of a porous substrate within a body of the cartridge, and an electrode incorporated into the body of the cartridge such that when the porous substrate is disposed within the cartridge, the electrode connects to the porous substrate;
- loading a sample onto the porous substrate;
- activating the electrode once the electrode is in contact with the porous substrate to thereby generate ions of the sample;
- and
- analyzing the ions of the sample.
A method for analyzing a sample, the method comprising:
- providing a cartridge configured to hold a porous substrate and an electrode that operably connects with the porous substrate when the porous substrate is at least partially disposed within the cartridge, wherein the cartridge further comprises a bottom portion and a detachable cover, and the cartridge is configured such that the bottom portion is configured to hold the porous substrate and the cartridge is configured such that voltage is not supplied to the porous substrate in the cartridge until the detachable cover is connected to the bottom portion;
- loading a sample onto the porous substrate;
- activating the electrode once the detachable cover is connected to the bottom portion to thereby generate ions of the sample;
- and
- analyzing the ions of the sample.
