Description

technical field [0001] The invention relates to a adopting device, in particular to a sampling device for headspace testing, which uses semiconductor refrigeration as a cold source. Volatile (flammable and explosive) gases can be condensed into liquids under semiconductor refrigeration conditions, and samples can be collected for analysis. Background technique [0002] Those with dangerous properties such as explosion, flammability, poison, corrosion, and radioactivity, which can cause combustion, explosion, and accidents such as personal casualties and property losses under certain conditions during transportation, loading and unloading, production, use, storage, and storage Chemical substances are collectively referred to as chemical hazardous substances. With the development of science and technology, people's safety awareness of production environment and living environment is getting deeper and deeper. More and more attention has been paid to environmental protection....
