  • Spillage detector for liquid chromatography systems
    Patent number: 4591838
    Abstract: 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).
