Tunable diode laser spectroscopy for gas detection inside scattering media

Summary, in English

The present communication is mainly focused on molecular oxygen detection in porous organic matter, through a tunable diode laser spectroscopy. Initial measurements on wood were preformed in order to illustrate the influence of the density and anisotropy of the sample on the GASMAS-signal. Additional measurements were performed on horticultural produces, in which the concentration of the molecular oxygen gas is of crucial importance for the ripening process and the quality of the produces. The methodology presented is general and can be applied to a large number of problems concerning gas exchange in porous materials, which can be of interest in applications ranging from biological and medical to industrial and pharmaceutical
