Title: ANALYZER AND A METHOD FOR ANALYZING CARBON (C) AND SULFUR (S) IN METALS
Abstract:
The invention relates to an analyzer and to a method for analyzing carbon and sulfur in metals and in other inorganic substances, comprising a vertical combustion tube having an external induction coil, a charging device for inserting a specimen crucible for the specimen into the combustion tube in the region of the induction coil, and an oxygen supply line and a carrier gas supply line at the upper end of the combustion tube. The charging device feeds the specimen from the upper end of the combustion tube, the combustion products are discharged at the lower end of the combustion tube, and the oxygen supply is done by way of an oxygen lance having a baffle, which closes off the cross-section of the combustion tube above the specimen crucible, leaving an annular gap to the inner side of the combustion tube, via which a carrier gas flowing around the crucible can be supplied.
