  • Features
    • Preparation of adsorbate by evaporator.
    • Use stainless steel and thermostatic control module as manifold. Constant temperature range: room temperature to 50oC.
    • Effective cold trap system prevents vapor from polluting vacuum pump and environment.
    • FFKM (Perfluoroelastomer) O rings for banner sealing performance.
  • Applications
    • Measurements of BET surface area and pore size distribution.
    • Measurements of various gas and steam adsorption isotherms.
    • Testing of isosteric heat of adsorption.
    • Determination of selective adsorption coefficient.
  • Main Parameters
    • Parts Vapor 200C Vapor 100C Vapor 100B
    Testing Principle The static volumetric method
    Data Features BET surface area: ≥ 0.01 m2/g
    Mesopore: 2 - 500 nm (BJH)
    Micropore: 0.35 - 2 nm (t-plot, DR, MP,DA, HK ,SF)
    Physical Adsorbate N2, Ar, Kr, CO2
    Vapor Adsorbate Carbon monoxide, ammonia, and a substance that is liquid at
    room temperature.(Except corrosive, hyper-toxic, hazardous gas)    		 Same as Vapor 200C and Vapor 100C,
    but p0 is greater than 1KPa
    Physical Adsorption
    Temperature    		 77K, 87K
    Vapor Adsorption Temperature 0 - 50oC
    Steam Recovery Cold trap in analysis station Double cold trap in analysis and pretreatment station
    Pretreatment Vacuum in-situ pretreatment Separate preposition and vacuum in-situ pretreatment
  • Essential Parameters
    • Evaporator Phase of adsobate transforming from liquid to gas by evaporator in room temperature, implements test requirements
    Adsorption Pressure P/P0is less than 1 (P0is saturated vapor pressure of adsobate in adsorption temperature)
    Vacuum Pump Special corrosion – resistant two stage rotary vane vacuum pump, molecular pump
    Pressure Sensor 1000 Torr, 10 Torr, 1Torr
    Sorption Temperature -196oC is provided by liquid nitrogen in low temperature Dewar flask; 0 - 50oC is provided by thermostatic water bath.
    Number of Gas Inlet Providing separate gas intakes according to customer requirements. (Number of intakes is multiples of 4).
    Gas Recovery Effective cold trap system prevents from polluting vacuum pump and environment by vapor.
    Pretreatment Vacuum in –situ pretreatment, temperature ≤400oC ±1oC.
