Technological advances have motivated researchers to transition from traditional gas chromatography/isotope ratio mass spectrometry to rapid, high‐throughput, laser‐based instrumentation for N₂O isotopic research. However, calibrating laser‐based instruments to yield accurate and precise isotope ratios has been an ongoing challenge. To streamline the N₂O isotope research pipeline, we developed the calibration protocol for laser‐based analyzers described here. While our approach is targeted at laboratory soil incubations, we anticipate that it will be broadly applicable for diverse types of stable isotope research.

一种校准基于激光的 N2O 同位素分析仪用于土壤生物地球化学研究的方法

技术进步促使研究人员从传统的气相色谱/同位素比质谱法转变为用于 N ₂ O 同位素研究的快速、高通量、基于激光的仪器。然而，校准基于激光的仪器以产生准确和精确的同位素比一直是一个持续的挑战。为了简化 N ₂ O 同位素研究管道，我们开发了此处描述的基于激光的分析仪的校准协议。虽然我们的方法针对实验室土壤孵化，但我们预计它将广泛适用于各种类型的稳定同位素研究。
