PURPOSE:To collect the fraction in safety while preventing the leakage of discharging liquid by opening a liquid discharge valve only when both sensors, indicating the longitudinal and lateral directions, recognize predetermined positions. CONSTITUTION:A discharge nozzle 1 is fixed slidingly to a longitudinal rail 11 which slides, while keeping the perpendicularity, along a lateral rail 12 secured to a liquid chromatography system. Since the longitudinal rail 11 slides along the lateral rail 12 and the nozzle 1 slides on the longitudinal rail 11, the nozzle 1 can move to the positions of all liquid collecting bottles 2, i.e., from the position A1 to the position J10. A longitudinal sensor 41 and a lateral sensor 42 are disposed, respectively, at the lower end parts of the lateral and longitudinal rails 12, 11. A liquid discharge valve is opened only when both sensors 41, 42 recognize predetermined positions. |
