BET Surface Area Analysis is an important tool for characterizing the wide range of powdered samples. It finds use in variety of fields such as

  • Adsorbent (such as activated carbon, silica gel, activated alumina, molecular sieves, calcium silicate, zeolite, etc.)
  • Ceramic raw materials (such as alumina, zirconia, silicates, aluminium nitride, silica,silicon nitride, quartz, silicon carbide, etc.)
  • Rubber material reinforcing agent (such as nano calcium carbonate, carbon black, silica, etc.)
  • Pharmaceuticals
  • Battery Materials
  • Metal oxides
  • Nanomaterials
  • Catalysts

We have installed JW-DA Multipoint BET Surface Area Analyzer in our application laboratory in Mumbai. We can analyze customer samples at nominal charges. The salient features of the JW-DA system are

  1. Model: JW-DA
  2. Principle: Low-temperature adsorption, desorption at room temperature; flow chromatography
  3. Function: BET surface area single point, Multi-point, Langmuir surface area, Reference comparison method
  4. Structural Features: Four analysis stations, four samples can be tested simultaneously. Pretreated independently
  5. Pressure Range: 0.05 - 0.35MPa
  6. Sorption gas: Nitrogen (99.999%)
  7. Carrier gas: Helium (99.999%)
  8. Test Range: Surface area > 0.01m2/g no upper limits
