Gold APP Instruments​​

​ABOUT US

Gold APP Instruments Corporation Limited is a dedicated manufacturer for gas adsorption (physical & chemical) analyzers, thermogravimetricis analyzers and particle size analyzers, is a high technology company that combines state-of-the-art hardwares and professional theories for nano-materials determination. We originates and serves the China Weapons System, relies on advantages of local talented human resource and weapons system technology and devotes into scientific instruments development, production and sale. To research and develop fully automatic and intelligent laboratory determination analyzers, provide international standards, high cost performance instruments for R&D institutes, universities and manufacturing enterprises are our unchanged mission.

Our analyzers cover:

  • F-Sorb X400CE series specific surface area analyzers, bases on flowing gas principle
  • V-Sorb X800 series BET surface area and porosimetry analyzers, relies on static volumetric adsorption principle 
  • H-Sorb X600 series high pressure and temperature adsorption analyzers, by volumetric adsorption principle
  • G-DenPyc X900 series helium pycnometer density analyzer, with supports of gas displacement principle
  • C-Sorb series chemisorption analyzers
  • Thermal analysis analyzers for TG/TGA/DTA/DSC/DIL etc.
  • Laser diffraction particle size distribution analyzers for wet/ dry/ spray etc. materials.


Gold APP Instruments Corporation Limited scientists have revolutionized measurement techniques and designed instrumentation to enable the accurate, precise, and reliable characterization of powdered and porous materials like for battery/ fuel cell materials, catalysts, pharmaceuticals, ceramics, carbons, zeolites, projectile propellant, cosmetics, aerospace, nanotubes, medical implants, pigments and foodstuffs, indeed any solid whose performance depends on some interaction with its surroundings through its surface. 


Also, provide samples testing like:

  • Single&multi-points BET (Brunauer-Emmett-Teller) surface area, Langmuir/ t-plot surface area; 
  • Mesopore and micropore size, pore size distribution analysis with BJH (Barrett-Joyner-Halenda), SF (Saito-Foley),      DR (Dubin-Radushkevich), DA (Dubinin-Astakhov), MP, HK (Horvath-Kawazoe) etc. methods; 
  • Gas pycnometer helium or nitrogen true (real/absolute/skeletal/apparent) density measurement, open and closed        porosity testing;
  • PCT, PCI, adsorption and desorption isotherms utilizing gases hydrogen, methane, and carbon dioxide etc.;
  • Thermal analysis like thermogravimetric analysis (TG), differential thermal analysis (DTA), differential scanning            calorimetry (DSC), Dilatometry (DIL) etc.; 
  • TPD, TPR, TPO, TPRx, TPSR, pulse chemisorption, pulse calibration etc. by chemisorption;
  • Particle size & particle shape & particle size distribution

 
 
All series of instruments had been approved by ISO 9001: 2018, CE, national calibration certificates etc. these make it hold the biggest market share in China from year of 2008, and also exported over 50 countries like USA, Canada, Russia, UK, Germany, France, Nigeria, Iran, Saudi Arabia, India, Malaysia, Thailand, Indonesia, S. Korea, Australia, New Zealand, Brazil, Mexico and so on.
