    • Apparatus for preparing solutions of solid samples for wet chemical analysis comprising an overflow dissolving vessel divided by an overflow baffle into at least two chambers, means for maintaining a constant stream of solvent flowing successivefully through the chambers of said overflow dissolving vessel and a metering conveyor scale for continuously metering a measured amount of solid sample to be analyzed to the overflow dissolving vessel, said metering conveyor scale comprising a conveyor for continuously introducing solid sample into the dissolving vessel, a vibratory feeder for continuously supplying solid sample to the conveyor at a controlled rate and an overflow funnel for supplying a controlled amount of sample to the vibratory feeder; deflecting baffles and agitators are provided to promote mixing and dissolution of the sample and means are provided for automatically withdrawing a sample of solution for analysis from the chamber remote from the chamber into which the solid sample is introduced.
    • 用于制备用于湿化学分析的固体样品的溶液的装置,包括溢流溶解容器,其由溢流挡板分成至少两个室,用于保持恒定的溶剂流连续流过所述溢流溶解容器的室和计量输送器秤 为了将测量量的待分析的固体样品连续计量到溢流溶解容器,所述计量输送机秤包括用于将固体样品连续引入溶解容器的输送机,用于以可控速率将固体样品连续供给到输送机的振动进料器 以及用于将受控量的样品供应到振动进料器的溢流漏斗; 提供偏转挡板和搅拌器以促进样品的混合和溶解,并且提供装置用于自动地从远离固体样品引入的室的室中抽出用于分析的溶液样品。
