The sample is completely and instantaneously oxidised by flash combustion, which converts all organic and inorganic substances into combustion products. The resulting combustion gases pass through a reduction furnace and are swept into the chromatographic column by the helium carrier gas. The gases are separated in the column and detected by the thermal conductivity detector which gives an output signal proportional to the concentration of the individual components of the mixture. ThermoFinnigan is part of Thermo Fisher Scientific."@en ; skos:inScheme ; skos:notation "SDN:L22::TOOL0532" ; skos:note "accepted"@en ; skos:prefLabel "Thermo Finnigan EA 1112 Flash Elemental Analyser"@en ; skos:related .
