Disclosed is a demountable tube for a plasma torch assembly, such as an ICP torch assembly. The tube includes an open tubular body for radially surrounding a plasma within the tubular body. The tubular body may comprise a wall; and a mounting feature projecting from the tubular body for at least one of: (i) controlling alignment of the tubular body with respect to a mounting portion of the torch assembly, and (ii) releasably securing the tubular body to a portion of the torch assembly. The tubular body may also have a transmission zone that is partially devoid of said wall and includes at least one hole through said wall. The tube may be opaque. A plasma torch and ICP spectroscopy system are also disclosed.

A method and a device for generating a plasma in atmospheric- pressure, low-temperature conditions are described herein. The device described for the generation of the plasma comprises a first pair of electrodes, each of which separated by a dielectric layer and externally positioned with respect to a tubular duct where the gas flows, and a second pair of electrodes, also in this case each of which separated by a dielectric layer and externally positioned with respect to said tubular duct where the same gas flows downstream with respect to the first pair with respect to the direction of the flow. A high-frequency excitation is applied to the first pair of electrodes while a Radio-Frequency excitation is applied to the second pair of electrodes. The plasma generated in this manner emerges from the gas flow at the outlet of the transport duct. The high-frequency excitation can be applied in pulse trains and the Radio-Frequency generator is substantially activated in said pulse trains for the purpose of limiting the thermal load on the treated substrate. Chemical precursors and reagents can be added to the plasma as vapors or aerosols by means of a central transport duct coaxial with the tubular duct for the gas.

There is provided a plasma generation device capable of suppressing arc discharge in which discharge is localized to cause a high temperature, and allowing atmospheric discharge plasma to be stably generated with a high generation efficiency in a low temperature at about a room temperature without being spatially biased. The plasma generation device arranged with a plurality of electrodes facing each other includes a discharge position control unit, which is arranged between each of the plurality of electrodes, and is formed by containing an inverse characteristic material composed of a fluid having polarizability and a property that dielectric constant decreases with an increase in temperature, in a container formed of a dielectric material, wherein the inverse characteristic material is spaced apart from each of the plurality of electrodes.

Certain embodiments described herein are directed to devices that can be used to sustain a low flow plasma. In certain examples, the low flow plasma can be sustained in a torch comprising an outer tube and an auxiliary tube within the outer tube. In some examples, the auxiliary tube comprises an effective length to match the shape of a low flow plasma sustained in the torch using a flat plate electrode. Methods and systems using the torches are also described.
摘要:
A microwave plasma generating apparatus (10) has a microwave cavity (20) coupled to a microwave source (22) by a wave guide (24). Within the cavity (20) is a reaction tube (30) defining a plasma cavity (40). A gas inlet manifold (50) is provided at the top of the reaction tube (30), which is formed so as to introduce plasma gas in a swirled manner, that is, in the form of a vortex. This prevents overheating of the reaction tube (30).
