Many specific use cases rely on sensors and monitoring of compounds where the calibration gas is not commercially available or is not economically viable. The rare of non-retails calibration gases can in many cases be achieved with evaporation. Flowseg Fluid can dose any low viscosity fluid into evaporator and produce these calibration gases on demand, for the whole range of the sensor or monitor device.

For example isotope tests, heavy water evaporation, octamethylcyclotetrasiloxane into siloxane.

Furthermore, any two (or more) liquid reagents can be dosed in controlled manner into a passing stream og gas or gas mixture.
