To connect the reference gas supply and return lines use only such gas-contacted connecting
parts that are suitable for the connection and the reference gas.
The ow rate of the reference gas can range from 0.1l/min to 1.5l/min. We recommend a
ow rate of approx. 0.5l/min.
For devices without ow-type reference compartment, the reference cuvette is lled with
nitrogen and hermitically sealed.
