    Sammanfattning

    This study investigates the performance of a printed copper acetate based H2S sensor with irreversible electro-optical response. The sensitivity, long term stability, humidity effects, cross-sensitivity and selectivity of the H2S sensor were studied. High sensitivity, room temperature operation, good selectivity and reproducibility of the sensor make it a promising candidate for industrial use for example in the food packaging industry and in environmental monitoring. Furthermore, a simple optical indicator based on copper acetate for H2S sensing is also presented. The indicator was calibrated using grey scale for different concentrations of H2S.
