TY - GEN A1 - Hahn, Oliver A1 - Wilke, Olaf A1 - Jann, Oliver T1 - Characterization of air quality in museum show cases T2 - Indoor Air 2005 N2 - The present study comprises the characterisation of museum show cases concerning their hazardous potential for art objects. In order to estimate potential risks of damage the emission of volatile organic compounds coming from several construction materials is monitored and different air exchange rates from exhibit cases are determined. For the determination of the VOCs different methods were applied. The first step is a direct thermal extraction of the materials followed by emission test chamber measurements. The tracer gas method with N2O that is used in this study is a convenient procedure to investigate air exchange rates under working conditions greater than 0.05 d-1. The results of this study confirm the importance of the careful choice concerning building materials for show cases. Furthermore the analyses clarify that certain organic compounds might be a problem for the exhibits in show cases with low air exchange rates.
