Abstract

For an accurate indoor air composition analysis the most useful tool is represented by the combination of a manual SPME collection of samples and the subsequent gas chromatography/mass spectrometry characterization. This method is lengthy, expensive and moreover it cannot allow a prompt danger signal. In this paper, different classes of indoor air pollutants have been evaluated, focusing the attention on acid and basic compounds and comparing the efficiency of a commercial pH indicator to corrole response. The reactions induced by acids or bases onto the dye embedded membranes led to absorption spectra considerable changes. The computer screen photoassisted technique has been able to discriminate among the tested analytes, showing also low detection limits in the case of trimethylamine.
