    摘要: An indirect agglutination immunoassay includes the steps of providing, in a container, an immunoassay system comprising a test sample containing a desired analyte, and a reagent composed of magnetic particles or magnetic-material containing particles containing iron therein, wherein the magnetic particles or magnetic-material containing particles have been sensitized to allow specific binding to the desired analyte, and have a particle size in the range of 1 to 5 &mgr;m, with the content of the iron being in the range of 8 to 20 wt. %, precipitating the magnetic particles or magnetic-material containing particles by the application of magnetic force, allowing the container to stand at an inclination, and detecting the presence or absence of an immune reaction from the absence or presence of slippage observed of the precipitated magnetic particles or magnetic-material containing particles on the bottom of the container. An apparatus for conducting this indirect agglutination immunoassay is composed of the above container, a magnetic sedimentation device for magnetically precipitating the components containing the magnetic particles at the bottom of the container, and an inclination device for allowing the container to stand at an inclination after removal of the magnetic sedimentation device.

    摘要: The invention discloses a low NO.sub.x emission burner for use with an apparatus in which the material or materials are heated by the heat radiated from the radiation surface which is heated by the combustion by the burners. The secondary air injection ports or outlets are so arranged as to inject the secondary air upon the radiation surface to control the combustion, thereby reducing the release of NO.sub.x without producing CO and soot.
