Problems solved by technology

At present, seawater DIC is measured on-site after being sampled and stored, and taken back to the land laboratory for measurement. However, during the storage of the sample, its temperature, pressure, biochemical environment, etc. are significantly different from those of the on-site seawater, resulting in DIC measurement results. The actual difference is relatively large

Abstract

The invention relates to the technical field of ocean monitoring and in particular relates to a seawater carbon dioxide generation device capable of being used for measuring dissolved inorganic carbon in seawater and dissolved carbonate in other water samples. The seawater carbon dioxide generation device comprises a reactor body and a waste liquid discharge control system, wherein an acid adding hole, a seawater sample feeding hole, a washing water inlet and a CO2 gas outlet are formed in the top of the reactor body; a gas inlet and a waste liquid discharge hole are formed in the bottom of the reactor body; the waste liquid discharge hole is connected with the waste liquid discharge control system; the waste liquid discharge control system mainly comprises a pinch type electromagnetic valve. The seawater carbon dioxide generation device can be used for converting the dissolved inorganic carbon in the seawater into carbon dioxide and blowing out the carbon dioxide from the seawater, integrates the functions of sample feeding, acid adding, washing, waste discharging, gas blowing, gas discharging and the like, and is easy to automatically operate, simple in structure and convenient to operate.

Description

technical field [0001] The invention relates to the technical field of marine monitoring, in particular to a seawater carbon dioxide generating device, which can be used for the determination of dissolved inorganic carbon (DIC) in seawater and the determination of dissolved carbonate in other water samples. Background technique [0002] Global change involves two major fields: global climate change and global ecological environment change under human influence, among which the study of carbon cycle process is the key. The role of the ocean in global change is huge. The ocean carbon cycle is the core of global ocean flux changes, and the basis for studying the ocean carbon cycle is to accurately measure various parameters of the ocean. In recent years, great efforts have been made at home and abroad to study the accurate determination of marine parameters, but up to now, the special committee of the international IOC-SCOR still believes that the four key parameters in the mar...
