Abstract

The invention discloses volatile organic compound monitoring and sampling equipment which comprises a sensing device, a sampling device, a communication device and a control unit, wherein the sensing device is used for sensing the concentration of volatile organic compounds in ambient air and outputting a concentration signal; the sampling device is used for collecting gas in the environment; the communication device is used for receiving or transmitting messages; and the control unit is electrically connected with the sensing device, the sampling device and the communication device. The volatile organic compound monitoring and sampling equipment at least comprises a first sampling mode and a second sampling mode for sampling gases in the environment; in the first sampling mode, the concentration signal is received by the control unit, and when the concentration signal meets a first concentration value, the control unit starts the sampling device so as to collect the gases in the environment; and in the second sampling mode, when the control unit receives a sampling message by virtue of the communication device, the control unit starts the sampling device so as to collect the gases in the environment.

Description

technical field [0001] The invention relates to a sampling system, in particular to a sampling device for monitoring volatile organic compounds. Background technique [0002] The common volatile organic compounds (Volatile Organic Compounds, VOCs) can be further divided into eight categories according to their chemical structures: alkanes, aromatics, alkenes, halocarbons, esters, aldehydes, ketones and others . The main sources of VOCs are fuel combustion exhaust gas, industrial exhaust gas from transportation, vehicle exhaust, photochemical pollution, petroleum products, chemical solvents, etc. It is colorless and almost odorless in light concentrations, and has a similar odor to petroleum in high concentrations, and its composition can only be determined after testing. [0003] The Environmental Protection Agency of the Executive Yuan of Taiwan stipulates that the total volatile organic compound (TVOC) content is less than 0.56ppm. This ppm-level standard is quite small...
