    摘要： The invention relates to a microfluidic arrangement for metering one or more first metered amounts of liquid (A) and for separating the latter from a second amount of liquid (B), having the following features: the arrangement has a first channel and one or more second channels; the first channel has one inlet and one outlet; in the area of the outlet the arrangement has a capillarity, which is greater than or equal to the capillarity in the area of the inlet; the one or more second channels branch off from the first channel at one or more branch points; the one or more second channels have a greater capillarity than the first channel at the branch points; and the one or more second channels have a predetermined volume. In the arrangement as depicted in the invention a liquid is transported in the first channel from the inlet to the outlet. At the branch points one portion of the liquid at a time enters the one or more second channels and fills them completely with the first metered amounts of liquid (A). The portion of the liquid remaining after the last branch point in the first channel emerges as the second amount of liquid via the outlet from the first channel. The amounts of liquid (A) metered in the one or more second channels are separated from the remaining amount of liquid (B) by a gas, which is located in the first channel after filling all one or more second channels.

    摘要翻译： 本发明涉及一种用于计量一个或多个第一计量的液体（A）并将其与第二量的液体（B）分离的微流体装置，其具有以下特征：该装置具有第一通道和一个或多个 第二渠道; 第一个通道有一个入口和一个出口; 在出口的区域中，该布置具有毛细作用，其大于或等于入口区域中的毛细作用; 所述一个或多个第二通道在一个或多个分支点处从所述第一通道分支; 该一个或多个第二通道在分支点具有比第一通道更大的毛细作用; 并且一个或多个第二通道具有预定的体积。 在如本发明所述的布置中，液体在第一通道中从入口输送到出口。 在分支点处，一次液体的一部分进入一个或多个第二通道并用第一计量的液体（A）完全填充它们。 在第一通道中的最后一个分支点之后残留的液体部分作为第二量的液体经由第一通道的出口排出。 在一个或多个第二通道中计量的液体（A）的量通过在填充所有一个或多个第二通道之后位于第一通道中的气体与剩余量的液体（B）分离。
