摘要： A sample material to be dehydrated is enclosed in a container transmissive to microwave and air is past through the container under a microwave radiation to preferentially remove the water content of the sample. The dehydrated sample may be incinerated by switching the air supply to an oxygen supply under the microwave radiation.

摘要： A continuous tritium radioactivity measuring system is disclosed, in which a sample gas containing tritium is mixed with hydrogen gas, water vapor and lower hydrocarbon gases with the assistance of a catalyst for causing an isotope exchange reaction between the tritium contained in the sample gas and hydrogen. The resultant tritium gas and lower hydrocarbons containing tritium are removed from the remaining hydrogen water, and radioactivity detection is performed thereon.

摘要： A first and a second radioactivity detectors are used in series or in parallel which have substantially the same constructive features and the second radioactivity detector includes a fixed standard radioactive source therein. Sample gases each having a common radioactivity and having a different quenching effect are passed through the two radioactivity detectors sequentially to measure the effective radioactivities thereof to thereby obtain counting efficiencies of the two radioactivity detectors. A correction curve is drawn by putting the counting efficiency of the first radioactive detector along one axis of an orthogonal coordinates and the counting efficiency of the second radioactivity detector along the other axis of the coordinates. An unknown sample is treated in the same manner as the above to obtain the counting efficiency of the second detector for the unknown sample and a corresponding counting efficiency of the first radioactivity detector is obtained from the correction curve by the last counting efficiency of the second radioactivity detector. The quenching effect of the unknown sample is compensated for by using the corresponding counting efficiency of the first radioactivity detector.

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.
