Innova BET 比表面积分析仪 Model: iBET 200 系列

  • Analysis stations: 4-Station and 6-Station, fully automated operate
  • Surface Area and Pore Size by Gas Sorption
  • Adsorption / Desorption isotherm
  • Specific surface area: BET, Langmuir
  • Meso pore size distribution: BJH, Dollimore-Heal
  • Micropore area and volume: Dubinin-Radushkevich, t-Plot method
  • Micropore distribution: MP, HK, SF, DA, and compatible with NLDFT (Option)
  • Total pore volume and average pore width
  • Auto Degassing: full-automatic, program control degassing system
  • Built-in 3 touch PAD for both instrument control / Analysis and data reduction in real time. Remote control and service-after-sales may be performed with a dedicated mobile APP option.
  • The latest patented Constant Void Volume Technology: The servo-feedback elevator plus a 1000 torr transducer accurately controls the coolant level to keep the void volume constant despite of the coolant
  • Fully automated constant temperature system: The dual gas input preheating with 0.02 ℃ high-precision thermistor system, controls the temperature between 35-50 ℃ with real-time display of the temperature of the gas pipe and the manifold against errors caused by environmental factors.
  • PFC flow control valves: System evacuation is performed by a pre-set program; the evacuation rate may be adjustable to prevent powder intake into the system during initial evacuation and to increase the pumping rate as the system approaches higher
  • 32-bit digital electronics: The latest 32-bit chips and circuit boards were developed instead of typical 24-bit system, which lead that the precision of the transducers is superior to competitive units, and ensure the ultimate accuracy for characterizing samples by nitrogen adsorption with micropore or ultra-low surface area less 2 m²/g.
  • iBET-201A owns 1 mesopore/micropore samples ports with degassing additional six samples simultaneously by dedicated degassing station. The system is suitable to universities, research institutions and industrial R&D with analysis of surface area and pore size of super-microporous, or micro- and mesoporous Chemisorption is available.
