V-Sorb 4800S

V-Sorb-4800S is researched and developed by Gold

APP Instruments for single and multi-point BET

surface area, also with Langmuir surface area and

others related with SSA by using static volumetric principle.

Analysis Method: static volumetric nitrogen

adsorption principle

Single and multi-point BET surface area, Average

particle diameter estimation, t-plot external surface

area, True density analysis, Langmuir surface area,

carbon black (STSA), adsorption constant C

Measuring Ranges: 0.005m2/g to no known upper

limit (surface area)

Sample Ports: four samples’ analyzing;  four samples degassing with the obligatory V-Gas degasser.
