Abstract
A capillary for a mass spectrometry system is described. The capillary comprises a channel and a tip, and at least one of the channel and the tip comprises a carbon nanotube material that provides a hydrophobic surface.
Claims22
A capillary for a mass spectrometry system, comprising:
- a channel and a tip, at least one of the channel and the tip comprising a carbon nanotube material that provides a hydrophobic surface.
An ion source for a mass spectrometry system, comprising:
- a capillary configured to produce a spray of ions and comprising a carbon nanotube material that is hydrophobic.
An ion source for a mass spectrometry system, comprising:
- a capillary comprising a tip that comprises a hydrophobic material, the hydrophobic material comprising carbon and being substantially ordered;
- an electrode positioned adjacent to the capillary;
- and
- a power source in electrical connection with the capillary and the electrode, the power source being configured to apply a voltage between the capillary and the electrode.

A mass spectrometry system, comprising:
- (a) an ion source comprising:
- (i) a capillary configured to pass a sample stream, the capillary comprising a portion that is exposed to the sample stream when the sample stream passes through the capillary, the portion of the capillary comprising a carbon nanotube material;
- and
- (ii) an electrode positioned with respect to the capillary, wherein, when a voltage between the capillary and the electrode is applied, ions are produced from the sample stream and are directed towards the electrode;
- and
- (b) a detector positioned with respect to the ion source to detect the ions.
