Xgas
3 Design and Function
The BioPAT
®
Xgas combines one oxygen and one carbon dioxide sensor
featuring automatic compensation of humidity and pressure into one
compact analyzer. The gas to be analyzed flows through the integrated flow
adapter past the measuring chambers. During this process, the pressure,
humidity, oxygen and carbon dioxide concentration are measured.
The sensors measure the gases in the concentration ranges and under the
conditions for which they were designed; observe the → Technical Data.
The analyzer transfers the measurements to the control unit of the bioreactor,
e.g. the DCU systems of bioreactors Biostat
®
C Plus, B and B-DCU II.
The measurement and control system shows measurements on the display,
as configured in the settings. Observe the operating instructions for the
measurement and control system.
