Brochure

Features

  • Preparation of adsorbate by evaporator.
  • Use stainless steel and thermostatic control module as manifold.
    Constant temperature range: room temperature to 50 oC.
  • 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 - 50 oC
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/P0 is less than 1 (P0 is 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 -196 oC is provided by liquid nitrogen in low temperature Dewar flask;
0 - 50 oC 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 ≤400 oC ±1 oC.
