Short summary
We present a new correction and calibration protocol to improve the accuracy of nitrous oxide isotope measurements obtained using laser spectroscopy. Through laboratory experiments, spectral simulations, and an automated MATLAB (Matrix Laboratory) reduction scheme, we identify and correct biases caused by matrix gas composition, spectral interferences and instrument variability. This protocol enables researchers to produce more reliable isotope data and supports standardised isotope analyses across laboratories.
