Trace gas analysis from glazes by means of a compact photothermal deflection spectroscopy apparatus

摘要

A portable photothermal deflection spectroscopy apparatus for accurate analysis of gas mixtures containing volatile organic substances is presented. The main technical aspects of the photothermal deflection cell, and of the gas sampling equipment are discussed in details. Finally, we present a straightforward industrial application of the apparatus concerning the qualitative and quantitative analysis of the gas emissions from thermal treatment of ceramic glazes.
