Abstract:
1. A method for heat-decomposing a sample containing organics using a heat-decomposing device comprising a heat-decomposing appliance, said method comprising the steps of setting up the sample in the heat-decomposing appliance comprising, in the absence of firing means: a) a heating section in the form of an axially aligned tube, open at only one of two opposing axial ends, having a length between said opposing axial ends of at least 10 cm and being molded of material that withstands (i) corrosive gases, (ii) oxidative corrosion, and (iii) heating to a temperature of at least 600° C.; and b) an introducing section that cooperates with the open end of said tube to seal the open end and, thereby, close said heating tube for heat decomposition when containing organic components, said introducing section including means for introducing liquid through said introducing section into said heating tube when closed; heating of said appliance being effected only by external means, said appliance containing no source of heat; filling up the appliance with oxygen and closing the appliance, then heating the appliance to decompose the organics into testing components, followed by cooling the appliance, and thereafter introducing an absorbing liquid into said heat-decomposing appliance to absorb the testing components produced in said sample, said heat-decomposing device further comprising an appliance-installing section to install said closed heat-decomposing appliance, a heating means to heat-decompose the sample in said closed heat-decomposing appliance and a moving means to reversibly move said closed heat-decomposing appliance installed at said appliance-installing section to said heating means.
