Quantitative analysis of atmospheric copper corrosion productions by photoacoustic ftir spectrometry and photothermal deflection method

摘要

In this paper we will compare quantitative measurements obtained with FTIR-PAS and with the Mirage effect (PDS) by performing the PAS and PDS experiments with indentical copper patina samples. Furthermore a photothermal beam deflection sensor for physical in-field measurements has been constructed and sucessfully tested and compared to the conventional photothermal MirageMonoblock.
