FIELD: instrumentation.
SUBSTANCE: scope of application: for detection of small concentrations of functional carbohydrates in gaseous phase. The invention essence is as follows: the sensor device for selective detection of small concentrations of functional carbohydrates in gaseous phase contains at least one resistive sensor, designed so that to enable its heating and having a resistive sensor layer, and at least one surface ionisation sensor, designed so that to enable heating and including a sensor surface and an electrode positioned at a distance from the latter so that there is an electric field between them; the sensor layer of the resistive sensor is identical to the sensor surface of the surface ionisation sensor.
EFFECT: ensuring the possibility of developing a simply designed sensor device that can register small concentrations of functional carbohydrates in gaseous phase.
