Two sets of 2nd harmonic data for TDLAS/WMS applications
Oxygen is one of the most adverse gas that contaminates sterile drugs in glass medicine bottle, so it is of great significance to detect oxygen concentration for glass medicine bottle in order to ensure the asepsis of drug and the stability of ingredients. Wavelength modulation spectroscopy (WMS) is applied to achieve online oxygen concentration detection by the single-line spectrum analysis for the advantages of non-contact and high sensitivity. Unlike the gas detection in cells, the oxygen concentration detection in open-path optical environment is extremely challenging owing to the short light path length and random ambient noises. Consequently, we open two sets of second harmonic data to further TDLAS/WMS applications on this significant topic.
Two sets of second harmonic data are released to further TDLAS/WMS applications on the topic of headspace oxygen concentration measurement for glass medicine bottles. Instructions can be found in the file of "readme.txt" in the folder.
