Equipment: Quantachrome Quadrasorb Evo QDS 30
Technique: Brunauer-Emmett-Teller Nitrogen Physisorption
Acquisition year: 2015

Description: Brunauer-Emmett-Teller (BET) surface areas analysis device explicitly used to elucidate intrinsic porosity as well as specific surface areas of the sample. This device predominately utilized to determine the sample’s physical properties such as the size (micro-/macro-pore) and shape (for example, square/rhombus/hexagonal shape) of pore, permanent porosity though reversible isotherms analysis (from Type-I to -IV). The conventional nitrogen (N2) gas adsorption-desorption (at 77K) is the mostly used measurement from this device. This device consists of four ports and can capable to measure up to four samples independently in a single run. External activation unit enables the activation of pores from the sample through pre-vacuum and thermal treatment (at desired temperature), maximum temperature reachable up to 400 oC.

Specifications: 

  • Capable of measuring both micro- and macro-porous samples
  • Surface areas as low as 0.01 m2/g can be measured with the standard nitrogen system.
  • Can be able to reach very low vacuum up to 1.0*10-2 Torr.
  • External Activation stage (consists 6-ports) and the temperature control from rt to 400 oC
  • A decent cryogen Dewar (1-L) that can last up to 36 hours measurement time
