High
Pressure / High Temperature Adsorption : BELSORP-max
|
 |
| |
Description
The BELSORP-max is designed
for wide range adsorption isotherm for surface
area and pore size distribution analysis. It
can measure adsorption isotherms from relative
pressure as low as 1 x10-8 (N2 at 77K, Ar at
87K), using a 13.3Pa pressure transducer. Also
AFSM, the new method for free space measurement,
is applied and adsorption isotherm can be measured
with high accuracy. Chemisorption option enables
unattended chemisorption measurement from pretreatment
with step programs.
Features
- Specific surface area, pore
size distribution, vapor adsorption and
chemisorption (OP) can be measured.
- Adsorption measurement
from extremely low pressure (p/po=10-8 -
0.997)
- Up to 3 samples can be
measured simultaneously.
- Fully automated chemisorption
option is available.
- Kr adsorption is available
for low surface area material.
- Coolant level controller
is no longer necessary and high reproducible
data can be obtained (AFSM).
- BELSim, which analyze the
pore size distribution by NLDFT and GCMC
simulation method can be incorporated into
the powerful data analysis software, BELMaster.
- ISO 9277 and JIS
Z 8830 compliant
