《Qualitative and quantitative analysis of atmospheric methanol using a continuous-wave terahertz spectrometer》
In conclusion，four specific windows of transparency below 1 THz were utilized to remove the interference of water lines under normal pressure and temperature.Based on the method，qualitative and quantitative analyses of methanol samples with various concentrations in atmosphere were performed，which exhibit consistent absorption features and good regression results.The stability and frequency selectivity of this method based on the fast scanning THz-FDS have been demonstrated.However，with the decreased methanol，the goodness of fitting declined due to the weak absorption of samples.Increasing the length of the gas chamber and more precise absorption cross section calculations would improve the sensitivity and correctness of fitting.It should be noted that the weak water lines not observed in our study have been neglected during the selection of transparent windows.This study might provide some references for in situ detection.
