摘要:
An apparatus is disclosed including a tool comprising a first device for generating aerosol from a target, the first device being deployed through an opening in a tubing of the tool, wherein the tubing is provided with aspiration ports or fenestrations such that the generated aerosol is aspirated into the tubing via the aspiration ports or fenestrations. The aspirated aerosol is then transferred to a mass spectrometer for subsequent mass analysis.

摘要:
The tip of an electrically conductive probe 11 is brought into contact with a sample and captures the sample S under atmospheric pressure, a high voltage for electrospray is applied to the probe 11 while a solvent is supplied to the tip of the probe 11 that has captured the sample, and molecules of the sample S at the probe tip are ionized. A miniscule amount of a fine solvent droplet is supplied to the probe tip and slow electrospray is implemented. As a result, the size of the electrically charged droplet can be made extremely small and components within the sample can be analyzed extensively without selectivity. Further, in imaging over an extended period of time, electrospray is possible even in the event that the sample dries.

The invention generally relates to systems and methods for transferring ions for analysis. In certain embodiments, the invention provides a system for analyzing a sample including an ionizing source for converting molecules of a sample into gas phase ions in a region at about atmospheric pressure, an ion analysis device, and an ion transfer member operably coupled to a gas flow generating device, in which the gas flow generating device produces a laminar gas flow that transfers the gas phase ions through the ion transfer member to an inlet of the ion analysis device.

An object of the present invention is to extract a micro foreign body of a few µm, which may cause a product defect of a device or the like, and to subject the foreign body to a mass analysis at a favorable S/N ratio without any contamination. A micro sample heating probe includes a sample holder made up of two members different in diameter, a supporting part, and a terminal part. The sample holder includes a heating mechanism only in a limited part, and just a region extremely close to the micro sample being an analysis target is heated locally. Therefore, even when a contaminated substance is attached to the probe, such substance is not heated, thereby preventing a noise from occurring, and enabling an analysis at a quite favorable S/N ratio.

The invention provides glow discharge optical or mass spectrometers wherein a solid sample (13) may be mounted in a unitary source assembly (2) adjacent to a first electrode means (14). A second electrode means (7), spaced from sample (13) by an insulating washer (6), is also part of the source assembly (2) and engages with a discharge chamber (11) into which a discharge gas is introduced. A glow discharge (31) is maintained in chamber (11) by a potential difference applied between the first and second electrode means (14,7). In a mass spectrometer, ions formed in the discharge pass to a mass analyzer (36), while in an optical spectrometer, optical radiation from the discharge is spectroscopically analyzed. Particularly in the case of a mass spectrometer, the source assembly (2) may be mounted on an insertion probe (3) allowing it to be easily withdrawn from the vacuum envelope (1) to facilitate sample changing and maintenance.
