An element analysis device is provided, which can quantitatively analyze an H element contained in a sample gas with high accuracy. The element analysis device is provided with a heating furnace for heating a crucible having a sample contained therein while a carrier gas is introduced into the heating furnace to vaporize at least a part of the sample to generate a sample gas containing the H element and then deriving the sample gas with the carrier gas as a mixed gas and a mass spectrometer for quantitatively analyzing at least one element contained in the sample gas in the mixed gas that has been derived from the heating furnace, wherein the mass spectrometer quantitatively analyzes the H element contained as an H.sub.2O component in the mixed gas as the H element contained in the sample gas.

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.

A method is disclosed comprising obtaining or acquiring chemical or other non-mass spectrometric data from one or more regions of a target (2) using a chemical sensor (20). The chemical or other non-mass spectrometric data may be used to determine one or more regions of interest of the target (2). An ambient ionisation ion source 1 may then be used to generate aerosol, smoke or vapour (5) from one or more regions of the target (2).

Certain configurations are described herein of an instrument comprising a passive cooling device which includes, in part, a loop thermosyphon configured to thermally couple to a component of the instrument to be cooled. In some instances, the cooling device can cool a transistor, transistor pair, an interface or other components of the instrument.

A chemical analysis machine comprising a liquid phase chromatograph comprising, in turn, a chromatography nano-column with an inner diameter that is smaller than or equal to 100 μm, a mass spectrometer with an electronic ionization source, and a joining assembly interposed between the liquid phase chromatograph and the mass spectrometer. The joining assembly comprises a microcapillary tube having an inner diameter smaller than or equal to 50 μm and having a first end, which is directly connected to an outlet end of the nano-column so as to receive the liquid phase, and a second end, which is housed inside a vaporization microcannula where an inert gas flows. The vaporization microcannula is partially engaged by the microcapillary tube and has an end facing the inside of an ionization chamber of the mass spectrometer. The vaporization microcannula is subdivided into a first part, which is subjected to the action of a heating device, and a second part, which is kept at room temperature and has a length that is greater than or equal to 2 cm. The microcapillary tube occupies the inside of the entire second part of the vaporization microcannula and has an end portion that is arranged inside the first part and has a length that is less than or equal to 5 mm.

Disclosed herein is an apparatus for supplying reagent ions, for example ETD or PTR reagent ions, to a mass spectrometer. The apparatus includes a reagent material reservoir, coupled to a carrier gas supply, which delivers an entrained reagent vapor flow to an inlet of a mixing junction through a first flow restrictor. A control gas flow of carrier gas is delivered to another inlet of the mixing junction via a variable pressure regulator and a second flow restrictor. The outlet of the mixing junction is coupled via a third flow restrictor and a reagent transfer junction to an inlet of an ionizer, such as a glow-discharge ionizer. By dynamic adjustment of the output pressure of the variable pressure regulator, the flow rate of reagent vapor may be controlled over a broad range, even for reagent materials of relatively high volatility.

An apparatus for performing ambient ionisation mass and/or ion mobility spectrometry is disclosed. The apparatus comprises a substantially cylindrical, tubular, rod-shaped, coil-shaped, helical or spiral-shaped collision assembly; and a first device arranged and adapted to direct analyte, smoke, fumes, liquid, gas, surgical smoke, aerosol or vapour onto said collision assembly.

A constructed unit is fixed to a base by means of a plurality of support posts while being spaced from the base. The constructed unit includes an orthogonal acceleration unit. An incidence regulator unit is fixed to the base by a pair of support posts while being spaced from the base and the constructed unit. The incidence regulator unit includes, among others, a pair of blades that define a slit, and heaters for heating the pair of blades.

Portable instruments for analyzing elemental composition of liquid and solid phase materials by laser induced ablation spectroscopy are disclosed. The optical path of a single pulsed laser beam in the instrument is directed to a position depending on the phase of the sample material. Liquid phase samples are aerosolized before streaming to an analysis zone where they are dissociated in a plasma plume. A wide range of physical and chemical characteristics of liquid materials can be analyzed by the instruments. A large number of sites within solid phase sample structures are analyzed using a movable x-y-z stage in the instrument and the results are displayed in a chemical map.
