Off-Line Methods for Determining Air Quality in Museums

Abstract

This paper will examine three methodologies deployed in off-line research relating to air quality in museums. These methodologies made use of sensors based on the different chemical-physical
properties of various materials (corrosiveness, hardness and absorption). Various field applications were applied to case studies, which were performed in two museums in Palermo, Italy: the Regional Gallery of Palazzo Abatellis and the Diocesan Museum. This review of methodologies and sensors examines which protocol should be put into practice in museums in monitoring the air quality of display spaces and the conservation of cultural artefacts.
