  • 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

  • REAL-TIME AUTOMATIC ANALYSIS METHOD, FOR ORGANIC CONTAMINANT, USING REAL-TIME SPME-GC OR SPME-GC/MS ANALYSIS SYSTEM
    Publication number: 20170205382
    Abstract: The present invention relates to a real-time automatic analysis method, for an organic contaminant, using a real-time SPME-GC or SPME-GC/MS analysis system, the method comprising: a sample supply step for supplying consecutively and in real time a sample to a storing portion of a sample bottle through a sample supply line formed in a real-time SPME-GC or SPME-GC/MS analysis system; and a sample analysis step, such that the sample can be supplied consecutively and in real time, and thus a point of generation of a high-concentration organic contaminant is accurately and quickly identified and follow-up measures are taken.
