High purity ammonia center of Guangming research & design institute of chemical industry, its predecessor is the national "863" high purity ammonia research group established by Guangming Institute in 2000. In recent years the Ministry of Science, National Defense Committee and Dalian Municipal People's Government and the focus of institute funding and policy support, through to the ultra-pure gases, the electronic gases, high purity petrochemical gases, gases reference materials, gas purification and gas-related equipment and the key technologies in-depth research and exploration, and achieved certain achievement, especially the electronic gases in ultra pure ammonia, for the first time in the domestic LED production line, has formed the 1500t / a industrialization ability.

The center added a variety of advanced imported equipment such as: TIGER OPTICS trace water in ammonia ( 10^-9) analyzer, Agilent company GC-MS ( GC-MS ), ICP-MS, Shimadzu series chromatography, the United States DELTA F trace oxygen analyzer, XPDM dew point instrument, Thermo Electron's NO-NO₂-NO_x analyzer and balances imported from Germany, Switzerland, also purchased the United States type LPC-101-HP high pressure laser gas particle counter.

In the process equipment, complete with a variety of organic synthesis and ultra purification, catalyst performance evaluation, adsorption and distillation research and pilot production device, the full realized the perfect combination of the engineering research and the production of.

General Products

óSuperior products: ultra pure purity ammonia > 6.4N (LED grade); > 5.5N (IC and solar battery grade) design capacity: 1600t / a

Electron gas: high-purity chlorine, high purity arsine, high purity phosphine, high purity germane; high purity nitric oxide (semiconductor grade); high purity diborane; high purity boron trifluoride; high purity propane; high purity propylene; the purity of 6n h₂, he, ar etc…

High-purity gases: Synthesis and purification of gases is the advantages of professional for the center, with high efficiency gas separation equipment, such as different specifications of synthesis device, series of distillation tower, catalyst manufacture and evaluation device, According to the needs of users of synthetic or purified high pure organic ( inorganic ) gas, such as a variety of alkane, alkene, alkyne compounds, development of methyl bromide, carbonyl sulfide, methyl mercaptan, cyclopropane, allene, propyne, butylene special gas has been put into the market for many years. Developed high purity halogen gas, by many domestic users, to fully meet the quality requirements of electric light source.

Gas reference materials (Gas mixture): Guangming institute has the approval of national secondary standard substance (sample) 50 species approved by State Bureau of quality and Technical Supervision. The preparation of a variety of complex reference materials is central apparent characteristics, as with the gas distribution needs of the various raw materials are grown, so the standard (mixed) gas has cost-effective.

Typical representative of the standard gas: gas reference materials of sulfide series, gas reference materials of chlorine and chloride, ammonia (NH₃), gas reference materials of amine series, gas reference materials of nitrogen oxide, gas reference materials of cyanide ( HCN ), acetonitrile, aldehyde, acrylonitrile, gas reference materials of petrochemical, gas reference materials of liquid ampoule, etc.

            Ultra clean gas mixture for LED, solar energy: H₂-SiH₄, H₂-B₂H₆, H₂-PH₃, H2-AsH₃, etc.

Ultra-pure gas high-pressure purification equipment: purity 6N high pressure ultra pure nitrogen, ultrapure hydrogen, ultra pure helium, ultra purity argon purifier.

The cylinder inner wall special treatment: The inner surface coating, special oxidation, silylation technique, processing of the cylinders to ensure active gas reference materials such as gas reference materials of chlorine and chlorides, stable and reliable, in order to adapt to needs for the"ppb" level "active" gas reference materials, we are committed to the technical research.

Toxic gas detoxification technique: According to IC, LED production process large amounts emissions of toxic and harmful gases, in the domestic first to carry out SiH₄, Si₂H₆, AsH₃, GeH₄, PH₃, B₂H₆, H₂S, H₂Se, H₂Te and other dry detoxicating technology research, the technique has been widely applied to the use of toxic and harmful gas fields and departments such as the Institute of semiconductors of The Chinese Academy of Sciences, the China Aerospace corporation.

High purity chlorine purification device and chlorine decontamination: Industrial liquid chlorine as raw material, through a series of deep purifying set, the purity of chlorine gas is amounted to 99.9995%, effective removal of impurities such as H₂O, products are used in TFT-LCD, aluminum alloy processing, optical fiber off -OH production process.

Gas reference materials preparation device: According to years of gas distribution experience, combined with the current international technical achievement, designed to produce a sixth generation of standard gas preparation device, There are dozens of users to use our equipment, through the equipment to obtain gas related value-added services.

External training and services for gas reference materials technology: Using a rich theoretical and practical experience of nearly 30 years of front-line, planned to have industry-specific technical training, write series of internal control information such as the "Gas Reference Materials Learning Materials", "Maximum Preparation Pressure Calculation For Multiple Liquefied Complex Gas Reference Materials", " Compression Factor And Common Data Compilation For Gas reference materials preparation" and other technical information, the unique way. Has been trained hundreds of students for the domestic (foreign).
