Method and device for sampling emergent gas in natural spring water

Abstract

The invention provides a method and device for sampling an emergent gas in natural spring water, which finish the sampling of the emergent gas in the natural spring water through a gas extraction device with an opening, a gas conveying pipe with a valve, a gas collecting device with an opening and a drainage pipe. In the method provided by the invention, first, gas in the gas conveying pipe, gas in the gas extraction device and gas in the gas collecting device are removed and the opening of the gas collecting device is sealed before sampling; in the formal sampling process, the gas conveying pipe is respectively connected with the gas extraction device and the gas collecting device in a sealed manner, the drainage pipe and the gas collecting device are connected with each other in a sealed manner, the gas extraction device is immerged into a sampling water body to collect the emergent gas and collect the collected emergent gas in the gas collecting device through a natural drainage method or a negative pressure assistant drainage method. Because the gas collecting and storing process is sealed and continuous, interference from the outside gas is avoided and the sampling precision is assured in the invention; moreover, the sampling device is convenient to mount and simple and reliable to operate, and the gas collection can be independently finished by one person.

Description

technical field [0001] The invention relates to a gas sampling method and device, in particular to a sampling method and device for gas escaping from natural spring water. Background technique [0002] Ecological environment and climate change are currently one of the most concerned scientific issues. Spring water in nature, especially hot springs, contains a large amount of gas, which will eventually circulate and exchange with the atmosphere. It is of great theoretical value and practical significance to study the composition and formation mechanism of gases in natural water and their relationship with the environment. Determining the material composition of gases in water has always been a hot and difficult point in the field of geological and environmental research. People have done a lot of research on the composition of the atmosphere, but the research on the gas composition in water is much shallower. One of the important reasons is that it is restricted by the samp...
