GYA-4Q-type full automatic argon purifier can be used with direct-reading spectrometer, fluorescence spectroscopy, and glow spectrometers produced by many spectrometer companies such as Thermo, Germany Speicher, OBFL, Brooke; Switzerland ARL, Shimadzu, UK Arun, Beijing ng, Rayleigh, Wuxi Jin Yibo, Skyray, Yantai Dongfang, to enhance the reliability and stability of data analysis, and largely save the cost of high-purity argon. GYA-4NQ is particularly suitable for the direct reading spectrometers with nitrogen channels, while it is also used as protective atmosphere of the production of high-purity material (such as silicon, polycrystalline silicon, high purity metal) The purifier employs the principle that in the function of catalyst, trace oxygen in argon reacts with the carbon to product carbon dioxide to remove impurity oxygen in argon, then uses CMS to adsorb and detach H2O, CO2 and other impurities in argon, and with the function of alloy adsorbent, some reminder insert materials such as N2 in argon can be easily removed, finally get high purity argon. requirements for raw materials argon：General bottled pure argon, liquid argon, well-controlled pipeline argon Impurity requirements: O2≤1000PPm, H2O≤1000PPm. Pure gas output: purity: 99.9999% Impurity content: O2≤0.1PPm， H2O≤1PPm(or dew-point temperature≤－76℃) CO+CO2≤0.1PPm， S,P oxides≤0.1PPm. Dust particles（≥0.3μm）3-5／L. Working pressure：0.2-0.8Mpa. Processing capacity: 4NM3/h Machine features: * High active catalyst and purified gas after purification. * Double structure: one is working while the other is for generation and backup, realizing long-term continuous gas supply. * Process of pure gas blowing regeneration without hydrogen; don’t need a special room, safe. * Adoption of bellow seal valve with zero leakage instead of solenoid valve with high possibility of fault and leakage, more reliable. * Equipped with buffer tank to stabilize pressure and grantee the purity of the output gas, more compliant with spectrometers. * Nitrogen removal function is added to ensure the statistics stability when the direct-reading spectrometers with N channel analyzing N element. * GYA – 4N touch screen, test of the pressure and temperature at any time, adjustable working and regeneration cycle according to customers’ actual usage, save gas resource. * GYA – 4N, automatic switching function between working and regeneration, which is easily operated with high stability and reliability, avoid pollution caused by user’s fault operation.
