  • Real-time automatic analysis device for organic contaminant in water
    Patent number: 10408800
    Abstract: The present invention relates to a real-time automatic analysis device for an organic contaminant in water, the device having: an analysis apparatus comprising a solid phase micro-extraction device and a gas chromatography/mass spectrometry analysis device that have been traditionally used; a heating block; a sample bottle; a discharge unit; and a control unit. While using an analysis apparatus, being traditionally used, as it is, the real-time automatic analysis device for an organic contaminant in water accurately and quickly identifies a point of generation of a high-concentration organic contaminant by supplying a sample consecutively and in real time, takes follow-up measures, and easily performs a sensory analysis as well as a chemical analysis.
    Type: Grant
