摘要： An in-situ detection component for dissolved gases in liquid-phase media and preparation method of the in-situ detection component, the detection component is a drilled hollow-core light guiding device coated with a liquid-gas separation membrane on the outer surface. The liquid-gas separation membrane directly filters the gases dissolved in liquid-phase media into the drilled hollow-core light guiding device, where the laser interacts with the gases and generates the response signals that are transmitted through the hollow-core light guiding device, to realize the simultaneous dissolved gas separation and detection. The present application substantially reduces the time required for liquid-gas separation process in detection components, allowing for fast and accurate in-situ detection of dissolved gases, and integration of liquid-gas separation and detection procedures.
