  • Plasma torch with an adjustable injector and gas analyzer using such a torch
    Patent number: 6236012
    Abstract: This plasma torch (10) for the excitation of a gas for the purpose of analyzing it comprises a tubular injector (12), intended to be connected to a source for supplying a gas to be analyzed, and an external cylindrical sleeve (14) coaxial with the injector (12) and defining a cylindrical annular channel (32) for supplying a plasma gas, intended to be connected to a corresponding supply source for the purpose of generating a plasma (P). The diameter of the injector (12) can vary.

  • Process for the preparation of an ultra pure hydrogen peroxide solution by the ion exchange by sequence: anionic-cationic-anionic-cationic
    Patent number: 6214225
    Abstract: Provided is a process for the preparation of an ultrapure hydrogen peroxide solution. The process comprises at least one sequence which includes successively passing a solution to be purified through at least two beds of cation-exchange adsorbents (CEA) and two beds of anion-exchange adsorbents (AEA) according to the sequence: AEA→CEA→AEA→CEA Also provided is a plant for the implementation of the inventive process.
