Improved Methods for High Precision Isotope‐Ratio Infrared Laser Spectroscopy of Ecohydrological Waters With Organic Contaminants
A strategy of combining the two methods is proposed for high-precision isotope analysis of organic contaminated samples: post-analysis corrections of Picarro MCM data (δ<sup>2</sup>H and δ<sup>18</sup>O) and pre-treatment with SMEC method (δ<sup>2</sup>H and <sup>17</sup>O-excess). The improved methods in this study can provide sufficient accuracy and precision for isotope analysis of plant and soil waters, which can contribute to the fields of ecohydrology and agricultural sciences.
