In-Situ High-Low Pressure Infrared Reactor
Based on many years of laboratory experience in in-situ infrared catalytic
research, ISRI has developed an in-situ IR-reactor capable of operating at high
pressure (15 atm) and vacuum (10-5 torr). The IR-cell reactor design
allows for the transmission IR data collection under flow or static conditions
from room temperature up to 450oC. The low volume reactor is equipped
with exchangable windows to cover a wide range or IR frequencies. The catalyst
wafer is placed in a holder which has two heating elements to control the
sample's temperature without heating the reactor's walls, thus avoiding problems
related to the expansion of gasket material. The reactor can be fitted easily in
most sample chambers of commercially available IR spectrometers.
