A method is presented for the online measurement of methane in aquatic environments by application of membrane inlet mass spectrometry (MIMS). For this purpose, the underwater mass spectrometer Inspectr200-200 was applied. A simple and reliable volumetric calibration technique, based on the mixing of two end member concentrations, was used for the analysis of CH(4) by MIMS. To minimize interferences caused by the high water vapor content, permeating through the membrane inlet system into the… CONTINUE READING
