Carbon dioxide isotope ratio measurements of the temperature non sensitivity which is based on the laser

摘要

The device and manner in order to decide ¹³ C isotope ratios for ¹² C in the gas sample which contains carbon dioxide (and the kit which it is related) is. This invention the aforementioned sample chamber has the fact that laser light energy after the passing is detected from thing and the laser illuminant which introduce the gas into the gas sample chamber making light the gas sample chamber face, making use of the detector. Here, as for laser illuminant, wavelength opposite 2054.37 and 2052.42 nano meters; Wavelength opposite 2054.96 and 2051.67 nano meters; Or, wavelength opposite 2760.53 and 2760.08 nano meters; It is possible to fetch one or more inside.
