Abstract
The investigation of the new method for determining isotope ratios by infrared gas analysis has been continued.
The amount of carbon dioxide required for a 13C/12C analysis has been reduced. The sensitivity is now 0.005 at.% excess 13C in 20 mg CO2 and 0.008 at.% excess 13C in 8 mg CO2.
The method has been extended to the determination of the 15N/14N ratio in nitrous oxide (*NNO) and the sensitivity reached is 0.015 at.5% excess 15N in 6 mg N2O.
