| Abstract: | SUMMARIES. Results from laboratory and field testing of an early warning (EWO) sensor developed in the EU-funded MASTER project (EVK-CT-2002- 00093) are discussed. Laboratory testing shows a clear response to low concentrations of the single contaminant gases NO2, O3 and SO2. In a comprehensive European field test programme a corresponding effect to that seen in the laboratory was observed for indoor NO2. The main aim of the MASTER project is to develop a preventive conservation strategy including an early warning system, with an EWO sensor, for protection of organic objects in museums, historic buildings and archives. CONCLUSIONS. The EWO sensors developed in the EU MASTER project show a clear response to low concentrations of the single indoor contaminant gases, NO2, O3 and SO2, in the laboratory. In an ongoing comprehensive European field test programme a corresponding effect to that seen in the laboratory was observed for NO2. Real indoor SO2 concentrations are so low that effects were difficult to study. With more or equal amounts of indoor NO2 compared with O3, which was the situation observed indoors in most cases, the effect on the sensor depended on NO2 alone. This opens the possibility to calibrate the generic effect on the sensor against the effect on real organic museum objects using the effect of NO2 as an indicator of the effect of total environment. One should then do more research on the magnitude of the relative effect of NO2, O3 in mixtures with NO2, SO2 and especially organic acids on the sensor compared with that on real museum objects. |
