Hydrogen stable isotope analysis has been a valuable tool in the fields of geochemistry and ecological research as well as many other research fields. The methods are mainly divided into the dual‐inlet method (off‐line method) and continuous flow method. The dual‐inlet method is complicated and inefficient, but it is still important because of its high precision and wide application range. Although the continuous flow method improves the experimental efficiency, the memory effect is noticeable and the accuracy is reduced.

一种改进的密封石英管法，用于测定水中的氢同位素。

氢稳定同位素分析已成为地球化学和生态研究领域以及许多其他研究领域中的宝贵工具。这些方法主要分为双进样法（离线法）和连续流法。双入口方法虽然复杂且效率低下，但由于其高精度和广泛的应用范围而仍然很重要。尽管连续流方法提高了实验效率，但记忆效果显着且准确性降低。
