    • A row of (n+m) powder containers which contain powder for chromatography and a row of (n+m) solvent containers which contain solvent for partition are arranged closely in parallel to each other. 0): A predetermined quantity of sample solution is added to the m-th solvent container from the left. 1): The powder containers and the solvent containers of the same numbers from the left in the rows are coupled with each other to form a row of (n+m) pairs of the powder containers and the solvent containers. 2): The powder and solvent of each pair are mixed and stirred until components to be separated come into partition equilibrium. 3): The powder and solvent of each pair are separated and made to exist in the original containers of each pair. 4): The pairs are decoupled to form the row of the powder containers and the row of the solvent containers again, and the rows are shifted from each other by one container in the opposite directions alternately. The steps 1)-4) are repeated, completing one process composed of the steps 0)-4)+steps 1)-4). The process is repeated. Each time the rows are shifted, the leading container containing separated sample component is removed, and a new container is added to the rear of the row to keep the number of containers in the row constant. By this method, the samples can be separated by relatively small number of partition equilibrium steps.
    • 一排(n + m)个粉末容器,其中包含用于色谱的粉末和一排(n + m)溶剂容器,其含有用于分配的溶剂,彼此平行地排列。 0):从左侧向第m个溶剂容器添加规定量的试样溶液。 1):相互排列相同数量的粉末容器和溶剂容器彼此结合形成一排(n + m)个粉末容器和溶剂容器。 2):将每一对的粉末和溶剂混合并搅拌直至要分离的组分达到分配平衡。 3):将每一对的粉末和溶剂分离并存放在每对的原始容器中。 4):这些对被解耦以再次形成一排粉末容器和一排溶剂容器,并且这些排彼此交替地以相反方向彼此移位一个容器。 重复步骤1)-4),完成由步骤0)-4)+步骤1)-4)组成的一个过程。 重复该过程。 每次移动行时,都会删除包含分离的样本组件的前导容器,并将一个新的容器添加到行的后面,以使该行中的容器数量保持不变。 通过这种方法,可以通过相对较少数量的分配平衡步骤来分离样品。

    • A narrow neck bottle is washed and rinsed by a method comprising the steps of supporting the bottle in an upside down position, injecting water containing air bubbles, into the bottle through a tube extending through the narrow neck of the bottle, accumulating air released from the poured water in an upper space in the bottle and expelling air and water remaining in the bottle by the accumulated air. Apparatus for carrying out this method comprises an aspirator installed such that its discharge pipe is directed upwardly, and connected to the discharge pipe, and a support for supporting the narrow neck bottle such that when supported by the support, the narrow neck of the bottle engages against the tube and that a gap is formed between the inner bottom surface of the bottle and the free end of the tube.
    • 通过包括以下步骤的方法对狭窄的颈瓶进行洗涤和冲洗,所述方法包括以下步骤:将瓶子倒置位置,通过延伸穿过瓶颈的窄颈部的管将含有气泡的水注入瓶中, 将水倒入瓶子的上部空间,并通过累积的空气排出残留在瓶子中的空气和水。 用于执行该方法的装置包括一个吸气器,其安装成使得其排出管向上指向并连接到排出管,以及用于支撑窄颈瓶的支撑件,使得当由支撑件支撑时,瓶的窄颈部接合 并且在瓶的内底表面和管的自由端之间形成间隙。
