Mid‐infrared dissolved CO2 measurement system using the ultra‐compact multipass cell

To measure natural gas hydrate, a mid‐infrared dissolved CO2 measurement system is designed using the tunable diode laser spectroscopy with ultra‐compact multipass cell. The QCL laser of 4319 nm has a scanning range from 2315.05 to 2315.40 cm−1, which contains 12CO2 and 13CO2 for isotope measurement...
