Abstract
There is provided a compound electrode assembly for generating a plasma in a plasma chamber of a plasma discharge device. The compound electrode assembly includes a casing, a discharge electrode and a sealing compound. The casing is made of a dielectric material and includes at least one side wall and an end wall defining a closed end. The discharge electrode is mounted in the casing and is bonded to the end wall. The sealing compound surrounds the discharge electrode and extends within the casing.
Claims26
A compound electrode assembly for generating a plasma in a plasma chamber of a plasma discharge device, the compound electrode assembly comprising:
- a casing made of a dielectric material, the casing comprising at least one side wall and an end wall defining a closed end;
- a discharge electrode mounted in the casing, the discharge electrode being bonded to the end wall;
- and
- a sealing compound surrounding the discharge electrode and extending within the casing.
A plasma discharge device, comprising:
- a plasma chamber traversed by a gas flow path allowing a flow of a gas sample through the plasma chamber;
- and
- at least one compound electrode assembly, each of said at least one compound electrode assembly comprising:
- a casing made of a dielectric material, the casing comprising at least one side wall and an end wall defining a closed end;
- a discharge electrode mounted in the casing, the discharge electrode being bonded to the end wall;
- and
- a sealing compound surrounding the discharge electrode and extending within the casing.
24-39. (canceled)
A plasma discharge device, comprising:
- a plasma chamber;
- a hollow electrode assembly, comprising:
- a rod made of an insulating material, the rod being traversed by a gas channel extending longitudinally therethrough to introduce a gas sample into the gas chamber;
