    • There are practical difficulties in dosing a component of a composition (2) into its container (14), such as a personal care product into a hand-holdable dispenser on a filling line, due in part to the short time that is available for the operation. The difficulties can be ameliorated or overcome by employing dosing apparatus (4) in which the length of time that an in-line valve (9) is controlled by a feed-back loop in which the stream of liquid (18) dosed into the container (14) from a dosing nozzle (11) positioned above the container is scanned by a laser-generated beam (19) at frequent intervals from which the volume of liquid in a dose can be calculated and compared with a predetermined range to identify whether and the extent to which the period of time for which the valve (9) is open for a succeeding dose is altered.
    • 将组合物(2)的组分(2)投入其容器(14)中,例如将个人护理产品投配到灌装线上的手持式分配器中存在实际困难,部分原因在于短时间可用于 操作。 通过采用定量装置(4)可以改善或克服困难,其中通过反馈回路控制管线阀(9)的时间长度,其中液体(18)流入容器 (14)从位于容器上方的给药喷嘴(11)被激光产生的射束(19)以频繁的间隔扫描,从中可以计算剂量中的液体体积并将其与预定范围进行比较以识别 随后剂量打开阀(9)打开的时间段的改变程度。

    • A microvolume liquid handling system includes a microdispenser employing a piezoelectric transducer attached to a glass capillary, a positive displacement pump for priming and aspirating transfer liquid into the microdispenser, controlling the pressure of the liquid system, and washing the microdispenser between liquid transfers, and a pressure sensor to measure the liquid system pressure and produce a corresponding electrical signal. The pressure signal is used to verify and quantify the microvolume of transfer liquid dispensed and is used to perform automated calibration and diagnostics on the microdispenser. In another embodiment of the microvolume liquid handling system, a system reservoir is connected with tubing to a pressure control system for controlling the liquid system pressure in the system reservoir. The system reservoir is coupled to one or more microdispensers through a distribution tube having a branched section for each microdispenser. In this embodiment, each microdispenser is coupled to its own flow sensor and to enable a system controller to respectively measure and control the flow of liquid in the each microdispenser. Dispensing of a single sub-nanoliter drop can be detected in real time. As the result of dispensing the liquid in sub-nanoliter droplets, the dispensed volume can be precisely controlled. The dispenser automatically detects the liquid surface of the transfer liquid, automatically aspirate, analyze desired volume of the transfer liquid, dispense the transfer liquid without contacting the destination vessel or its contents, and automatically wash off the transfer liquid from dispensing system after each transfer. This system is capable of automatically sensing liquid surfaces, aspirating liquid to be transferred, and then dispensing small quantities of liquid with high accuracy, speed and precision. The system is pulsated at high frequency to prevent or eliminate clogging. Immiscible liquid between the transfer liquid and the system liquid reduces the required amount of transfer liquid needed for dispensing.
    • 微量液体处理系统包括使用连接至玻璃毛细管的压电换能器的微分配器,用于将转移液体灌注并吸入微量分配器中的正排量泵,控制液体系统的压力以及在液体转移之间清洗微分配器, 压力传感器来测量液体系统压力并产生相应的电信号。 压力信号用于验证和量化分配的转移液体的微量,并用于对微分配器进行自动校准和诊断。 在微体积液体处理系统的另一个实施例中,系统容器通过管连接到用于控制系统容器中的液体系统压力的压力控制系统。 系统贮存器通过具有用于每个微分配器的分支部分的分配管与一个或多个微分配器连接。 在该实施例中,每个微分配器耦合到其自己的流量传感器并且使系统控制器能够分别测量和控制每个微分配器中的液体流量。 可以实时检测单次亚纳升滴的分配。 由于以亚纳升液滴分配液体,可以精确控制分配体积。 分配器自动检测转印液体的液面,自动吸取,分析转印液体的所需体积,分配转印液体而不接触目的容器或其内容物,并在每次转印后自动从分配系统清洗转印液体。 该系统能够自动检测液体表面,吸取要传送的液体,然后以高精度,高速度和精确度分配少量液体。 系统以高频脉动,以防止或消除堵塞。 转印液体和系统液体之间的不混溶液体减少了分配所需的转印液体量。
