    • A spillage detector device for use in conjunction with fractionation of liquid chromatography systems which includes a spillage receiving enclosure (34) beneath the fractionation area. A sensing device (36) having a plurality of electrodes (46) of alternating polarity is mounted within the spillage receiving enclosure (34). Detection circuitry (38), responsive to conductivity between electrodes (46), is operatively connected to the sensing device (36). The detection circuitry (38) feeds into the output circuitry (38). The output circuit has relaying and switching circuitry directed to a solenoid (60), an alarm system (118) and a pump (4). The solenoid (60) is connected to the pliable conduit (22) of the chromatography system. The alarm system comprises an audio alarm (190) and a visual signal (120). A 115-volt power system interconnected with the pump (4), the solenoid (60), the sensing device (36), and the detection and output circuitry (38).
    • 一种与液相色谱系统的分馏结合使用的溢出检测器装置,其包括在分馏区域下方的溢出接收封闭物(34)。 具有交替极性的多个电极(46)的感测装置(36)安装在溢出物接收外壳(34)内。 响应于电极(46)之间的导电性的检测电路(38)可操作地连接到感测装置(36)。 检测电路(38)馈入输出电路(38)。 输出电路具有指向螺线管(60),报警系统(118)和泵(4)的中继和切换电路。 螺线管(60)连接到色谱系统的柔性导管(22)。 报警系统包括音频报警器(190)和视觉信号(120)。 与泵(4),螺线管(60),感测装置(36)以及检测和输出电路(38)互连的115伏电力系统。
