Water vacuum extraction device for hydrogen and oxygen isotope analysis and extraction method thereof

Abstract

This invention belongs to the field of isotope hydrology experimental data preprocessing technology, and relates to a water vacuum extraction device and method for hydrogen and oxygen isotope analysis. The device includes a heating assembly, a freezing element, a vacuuming assembly, and multiple water extraction units. Each water extraction unit includes a sample bottle, a collection bottle, and connecting pipes communicating with the sample bottle and the collection bottle respectively. The vacuuming assembly is detachably connected to the collection bottle of each water extraction unit. The heating assembly includes a heater and a heat-conducting component placed on the heater. The heat-conducting component has multiple receiving grooves, and the sample bottles of the multiple water extraction units are placed in the receiving grooves respectively. The collection bottles of the multiple water extraction units are all placed in the freezing element. In this invention, when the vacuuming assembly is performing vacuuming, the water extraction units do not interfere with each other, ensuring the accuracy of water isotope extraction.
