• humidfier with small dead volume to moisten the gas

For the zero point calibration of analyzers that are water vapor cross-sensitive, the humidifier vessel FP-BF in front of the gas cooler is used to humidify the N2 zero gas in order to take water vapour cross-sensitive errors into account. Before entering the cooler, the zero gas passes the humidifier and leaves the cooler saturated at a stable dew point as well as the sample gas, e.g. at 5 ° C. Test gases with water-soluble components must not be passed via the humidifier.
