O
2 and CO
2 are the gases whose rates of consumption or production are most frequently measured for the purposes of study and process control (energetic metabolism, substract utilisation, etc.). The measuring ranges of the GA analyser (0 to 10 or 15per cent for CO
2, and 21to 10per cent for O
2) have been chosen specifically for your application.
The system is based on well-proven, high quality transducers, and is characterised by an extremely reduced internal volume, to reduce overall response times.
O2 concentration in the sample is measured by means of a transducer based on the zirconium dioxide properties of this gas, whereas CO2 determination is based on the measurement of absorption of infrared (IR) radiation.
Solaris GA is equipped with an inlet line selector (multiplex) that allows the unit to be connected with up to 12 bioreactors, and includes a pump for gas sampling and a gas drying device.
The concentration values of two gases are visualised on the monitor, are analysed and represented graphically ON LINE, with subsequent culculation of the respiration coefficient.
