Abstract: In order to stabilize injection of water plasma, a vortex water flow generator forms a vortex water flow for passing arc discharge. The vortex water flow generator includes a cylindrical portion configured to form a vortex water flow along an inner circumference, a first middle partition and a second middle partition protruding from the inner circumference of the cylindrical portion. The first middle partition and the second middle partition respectively have an opening to include a center axis line position of the cylindrical portion. An opening of the second middle partition on the side of the positive electrode is larger than an opening of the first middle partition on the side of the negative electrode.

Abstract: In order to attain an efficient decomposition process by water plasma, a decomposition processor includes a water plasma generator which is configured to inject water plasma, from the injection port, by arc discharge generated between negative and positive electrodes; and a supply device configured to supply a decomposition target object to a water plasma jet stream injected from the water plasma generator, wherein the decomposition target object is decomposed by the water plasma. The supply device has a nozzle for providing the decomposition target object from a tip, and the negative electrode, the injection port, the positive electrode and the nozzle are arranged in that order along the center axis line of the injection port. The tip of the nozzle is placed inside of the water plasma jet stream.

Abstract: A vortex water generator forms a vortex water flow for passing arc discharge. The vortex water flow generator includes a cylindrical portion configured to form a vortex water flow along an inner circumference; first middle partition and second middle partition protruding from the inner circumference of the cylindrical portion, a rear partition formed in a rear end side of the cylindrical portion, and a front partition provided in a front end side of the cylindrical portion. Each partition has an opening to include a center axis line position of the cylindrical portion. Each opening has a different opening shape in size. The middle partition and the front partition have negative electrode side surfaces formed by tapered surfaces receding from the negative electrode as close to the center axis line. Arc-shaped beveled portions are formed between the tapered surfaces and inner circumferential surfaces of the openings.

Abstract: A reagent for performing a chemiluminescent reaction includes luminol or luminol derivatives, an oxidant, an electron mediator, and an enhancer. The enhancer is a nitrogen-containing fused heterocyclic compound having at least two nitrogen atoms. The present disclosure further provides a kit for performing a chemiluminescent reaction comprising the aforesaid reagent.
