1	Principle and application	The oxygen in metal and non-metal solid materials is detected by inert gas melting principle. In the determination of oxygen, the sample after weighing is placed in a graphite crucible and melted by heating at high temperature in the argon gas flow. The oxygen in the sample reacts with the carbon in the graphite crucible to produce carbon monoxide (CO). This mixture is sent by argon gas to the reformer, where the carbon monoxide (CO) is converted to carbon dioxide (CO2), and through the gas mixture after the reformer is sent to the infrared detection tank, where carbon dioxide (CO2) is detected. Rapid and accurate determination of oxygen content in steel, cast iron, alloys, copper, zirconium, titanium, rare earth materials, nanomaterials and other inorganic substances.
2	analytical range	Oxygen: 0.00001% ~ 20%(expandable measurement range)
3	analytical precision	Oxygen: 1ppm or RSD≤1% Note: not greater than the sample standard deviation or uncertainty shall prevail.
4	sensitivity	0.01ppm
5	parsing time	Usually 3 minutes
6	detecting system	Non-dispersive infrared detection system was used for oxygen analysis
7	Infrared detection system	1, the standard configuration oxygen analyzer is equipped with an independent infrared absorption pool, and the length and number of channels can be flexibly configured according to user needs; 2, motor: the modulation system adopts single-chip microcomputer control of high-precision stepper motor, to achieve long-term stability of the modulation frequency; 3, light source: infrared light source selection of efficient, long-life precious metal micro-infrared luminescent and gold-plated metal mirror; 4, constant temperature: the whole gas chamber for constant temperature control, to ensure the analysis of constant temperature, to ensure the measurement accuracy, the use of temperature compensation semiconductor detector, to ensure that the instrument by the outside influence is small, the baseline is very stable.
8	Sample weighing	0.01-1g,Sample size can be changed according to sample content
9	Pulse furnace	1, current 0 ~ 1500A, power: 10KVA, the highest temperature is higher than 3200ºC. 2, pulse electrode furnace heating temperature is high, using program control power, can provide constant power heating, slope heating, segmented heating and other program heating methods, improve the analysis accuracy. It is suitable for rapid analysis from low melting point materials such as aluminum alloy to high melting point materials such as tungsten alloy. The electrode is suitable for a variety of types of crucible, according to the release of different samples, can choose a variety of crucible including sleeve crucible, high temperature crucible, effectively reduce the user's use cost. The electrode cooling system adopts a single cycle independent cooling system, which can directly connect the circulating water or the external water cooling device, and has the characteristics of good cooling effect and high reliability.
10	gas circuit	1, the use of integrated whole machine design, open space, the gas path system connection route is greatly reduced, the whole gas path system is more concise and reliable. Gas components including solenoid valve, cylinder, gas pipe, gas joint all adopt imported components, solenoid valve life of more than one million times. The special lifting system with two-axis guide cylinder ensures the smooth lifting of the electrode, ensures the good contact between the graphite crucible and the upper electrode, and ensures the uniform force of the graphite crucible, which is conducive to long-term high temperature heating. Automatic blanking furnace head with air curtain protection and automatic air purging mechanism effectively ensure the accuracy of oxygen element analysis. The furnace head is a split structure, easy to disassemble and replace, and the lower electrode is made of high-temperature alloy material, long service life and low cost. (If the whole furnace head is used, the replacement of the electrode requires professional and technical personnel to operate, which is very troublesome). 2, the design of the sampling system is open, its advantage is that the pollutants are discharged from the top of the furnace, not into the system, easy to operate, the system sealing requirements are not high.(Closed, the gas path through a costly six-way valve to control, internal out.(Some companies have complex sampling device, there are two cylinders, such as the sample stuck, need to open the cylinder, difficult to take out). The micro-flow sensor is used to achieve high precision flow control, and the influence of analysis air flow changes on the analysis is minimized. Gas conversion through this valve, so that the valve is easy to break, dust and other pollutants are also easy to bring into the system). This injection device is simple and can be automatically injected, in case the sample is stuck, easy to remove

The sample weight is automatically entered into the software; 4. Channel setting is optional; 5, dynamic release curve drawing and storage, unloading; 6, the analysis results of a variety of correction modes, can be manually corrected, can also be corrected through the analysis results; Can be single point correction, can also be multi-point correction; 7, the data screening, average, standard deviation, relative deviation, etc.; 8, the new software can be based on user application, can design a number of calibration lines, greatly facilitate the use of users; 9, the host can and computer, printer, electronic day equal connection to achieve data transmission; 10. The analysis time and blank value can be adjusted, and the blank value of the melting agent can be automatically removed; 11, the user can store several analysis methods for different analysis samples. 12, can store a lot of sample weight (quantity is limited only by the computer hard disk capacity). 13, can output regular format results report. 14, can be connected with the user database, to achieve remote transmission of analysis results, easy to achieve the network management of analysis results. 15, can quickly carry out instrument blank determination. 16, sample number can be stored and edited. 17, can be applied to automatic sampling, to achieve automatic operation of the instrument. 18, oxygen can be arbitrarily set up high and low analysis channel to meet the analysis requirements of different content and different materials. Users can use the combination freely according to actual needs.
