Abstract: The present invention relates to the field of detection of dimethyltryptamine. In order to solve the problems in the prior art that liquid chromatography-tandem mass spectrometry for detection of dimethyltryptamine has high requirements for instruments and operators and is difficult to popularize and low in detection speed, the present invention discloses a dimethyltryptamine hapten, an artificial antigen and preparation methods and application thereof. The dimethyltryptamine hapten is obtained by a reaction of N,N-dimethyl-5-hydroxytryptamine as a precursor and glutaric anhydride. The artificial dimethyltryptamine antigen obtained from the dimethyltryptamine hapten can be used for preparing a dimethyltryptamine monoclonal antibody and a dimethyltryptamine colloidal gold-fluorescence test paper.
Abstract: A rotating seal-type liquid testing apparatus includes a lower cup component, an upper cup body, a top cover and a testing element. The lower cup component includes a lower cup body, a high liquid baffle, a low liquid baffle and a water-absorbing sealing plug. The low liquid baffle and the high liquid baffle divide a bottom of an inner cavity of the lower cup body into a reaction region and a cut-off region. An edge of a bottom surface of the inner cavity of the lower cup body is provided with a vent hole, and the vent hole is positioned in the cut-off region. The upper cup body is disposed in the lower cup body, a bottom surface of an inner cavity of the upper cup body is provided with a liquid outlet, and the liquid outlet is connected to the reaction region in the lower cup body.
