20140038304 | HIGH-TEMPERATURE FURNACE, USE OF A SPINEL CERAMIC AND METHOD FOR CARRYING OUT T(O)C MEASUREMENTS OF SAMPLES - The present invention relates to a high-temperature furnace for T(O)C measurement of a sample, which has a furnace housing which bounds a vaporization space and has a sample opening for the dropwise introduction of the sample and at least one flushing opening for introduction of a flushing liquid. According to the invention, the furnace housing is lined with a spinel ceramic on an inner side facing the vaporization space. By means of the spinel ceramic, the vaporization space is lined with a material which allows particularly high temperatures within the vaporization space and thus very complete combustion and is at the same time very resistant to temperature changes. This allows cleaning with a flushing liquid at essentially the operating temperature of the vaporization space and removal of deposited salts, in particular recrystallized organic salts, from the vaporization space in the flushing liquid in dissolved or undissolved form. Aging of the high-temperature furnace by deposited salts can thereby be avoided or at least significantly retarded. | 02-06-2014 |
