Description

technical field [0001] The invention relates to a portable analysis instrument, in particular to a detection instrument for rapidly collecting and detecting various toxic and harmful gases in the air. Background technique [0002] As early as the early 1980s, foreign developed countries conducted a series of studies on indoor air quality. According to research by the World Health Organization, indoor air pollution in some buildings is ten to a hundred times more serious than outdoor air pollution, and more than 2,000 harmful substances will Constitute the pollution of indoor air. After entering the 1990s, scientists and environmental workers widely pay attention to research and solve the problem of indoor air pollution with great enthusiasm. Since 1992, more than 30 international conferences with the theme of "Indoor Air Quality (IAQ)" have been held in the United States. [0003] A large number of experimental studies have shown that the total concentration of indoor pollu...
