LASER SAMPLING IN MAKING LOCAL DETERMINATION PROBLEM OF GAS-FORMING MIXTURES IN SOLID SUBSTANCES

The following methods and devices have been used: laser mass-spectroscopy, laser samling in inert gas flow, chromatographic separation, determination by means of solid-electrolyte cell: mass-spectrometers MSKh-5, IPDO-2, MKh 7904 A. Two basic schemes of performing the local analysis have been created and investigated: laser sampling in vacuum with mass-spectral indication of gas-forming impurities and laser sampling in inert gas flow with chromatographic separation and indication by means of solid-electrolyte cell. The local method complex for determination of the gas-forming impurities. The methods have been used for analysis of the industrial objects. The methods have been used in some research institute. The introduction of methods enabled to select the optimum conditions of technological processesAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
