1. the aeration supersonic extracting method being used for analyzing detection, it is characterised in that:

  • will fill and analyze detection sampleContainer is placed in the ultrasonoscope equipped with sonification medium solution, then external separate gas is utilized gas tube and Aerating needle or fillsGas porous ware, to filling gas in the container bottom inflation analyzing detection sample, airlift agitation extract and increase extractantThe scale of construction, can carry out multiple pipeline, multiple conventional analysis container, more organize dissimilar sample and extract simultaneously;

    Concrete operation step is such asUnder;

    (1) gas piping is installed;

    is provided gas or compressor pressurization to provide gas by gas cylinder, is fitted through air relief valve regulationResultant pressure, the multipath gas of flow, multipath gas respectively by valve or clip by multichannel gas tube, many with Aerating needle or inflationHole ware connects, then inserts in the container filling extractant and test sample product by this Aerating needle or inflation porous ware, Aerating needle or fillThe gas outlet of gas porous ware is placed in the bottom of container;

    (2) ultrasonic extraction;

    the container respectively filling test sample is placed in equipped with in the ultrasonoscope of medium solution, good and sound fixedPosition plate, is plugged breather, opens ultrasonoscope, carries out ultrasonic extraction;

    To sufficiently large container, it is possible to the most built-in superSonic generator, carries out ultrasonic extraction;

    (3) inflate to container;

    open main valve, regulation air relief valve and the valve of Ge Lu gas or clip, be filled with gas to container bottomBody, makes the contained extractant of each container and extract sample when gas rises entrainment of rolling, stirring, and makes in extractantKeep a large amount of gas;

    (4) solid-liquid separation;

    according to sample granular size, character, is respectively adopted mesh screen, filter cloth, filter paper, filter membrane filter or take outFilter, or use ultrafiltration, centrifugal separation technology to carry out single or multiple solid-liquid separation, i.e. obtain extracting solution.
