Description
Based on the vibrational-rotational absorption spectra of gas molecules in the infrared region, we are dedicated to developing precision measurement devices for gas concentration and isotope abundance. We aim to achieve direct traceability for gas concentrations and isotopes and to explore standard gas transfer methods that do not require gas cylinders. Through technological innovation, we seek to reduce the cost of laser spectroscopy sensors, thereby promoting the widespread commercial use of laser spectroscopy analyzers in industrial, medical, and environmental applications.
In line with this, our developed laser-based carbon-13 isotope analyzer can measure CO2 concentration and δ13C in carbon dioxide, with a δ13C detection limit better than 0.03‰, while also offering rapid detection capabilities. The carbon-13 isotope analyzer plays a crucial role in various fields, including biomedical sciences, environmental monitoring, and scientific research.
