Brief introduction
ON-330 oxygen nitrogen analyzer with the protection of inert gas, pulse electrode melting furnace for sample decomposition, infrared absorption method for the determination of oxygen, thermal conductivity detection of nitrogen, determined the content of the three elements of oxygen, nitrogen in a single instrument.
Pulse furnace electrode inert gaseous protection ON-330 oxygen nitrogen analyzer configuration power 8.0KW, highest temperature can reach more than 35 DEG C, pulse furnace electrode by programmed temperature, selection of power control and current control heating control mode, decomposition of samples to achieve the optimal melting, at the same time, according to the elemental analysis to determine the inert gas helium or nitrogen as the carrier gas, such as black metal, nonferrous metal, ceramic materials, superconducting materials, semiconductor materials of various kinds of metal non metal material sample temperature thermal decomposition,the oxygen element in sample will react with carbon element in graphite crucible and generate CO, meanwhile, nitrogen element will escape as form of N2. Those mixed gas will be carried to transform furnace by
carry gas where CO will be transformed as CO2.After that, mixed gas will be carried to infrared detecting system to measure CO2, then remove CO2. After removing CO2, the N2 will be carried to thermal conductivity detector to detect N2. The infrared signal detection system and thermal conductivity detection system will be measured after amplification and A/D conversion processing, sent to the computer for data processing, to calculate the content of oxygen, nitrogen in the sample.
