Determining Biogenic Content of Biogas by Measuring Stable Isotopologues (12)CH(4), (13)CH(4), and CH(3)D with a Mid-Infrared Direct Absorption Laser Spectrometer
A tunable laser absorption spectrometer (TLAS) was developed for the simultaneous measurement of δ(13)C and δD values of methane (CH(4)). A mid-infrared interband cascade laser (ICL) emitting around 3.27 µm was used to measure the absorption of the three most abundant isotopologues in CH(4) with a s...
