ENDLESS SAMPLE BOTTLE FOR AUTOMATIC WATER SAMPLER

摘要

PROBLEM TO BE SOLVED: To drain water from inside a water sample bottle without using a drain pump or solenoid valve by mounding a U-shaped siphon tube to the water sample bottle of an automatic water sampler. ;SOLUTION: The drain speed of a U-shaped siphon tube 1 matched with the water sampling speed of an automatic water sampler approximately at 2000-3000 ml/min and is set approximately at 2000 ml/min. The siphon tube 1 is made of an acrylic resin or of glass, teflon, or the like when resistance to chemicals is needed. The treatment of the and of the siphon tube 1 is determined by a combination of various shapes by taking into account the amount of insoluble matter in a sample and drain speed. Sample bottle 2 are mounted to an automatic water sampler and arranged on a bottom base. The sample bottles 2 (for example, 24 pieces of them) are arranged at an outer circumferential part, the siphon tubes 1 are gathered at an inner circumferential part, and drainage samples are gathered at one location to enable efficient drain. When the automatic sampler is halted at the time when a pollutant flows in a river or the like, it is possible to obtain as many as 24 samples any time for 24 hours and to specify the type of the pollutant, causes, a pollution source, etc., by analyzing the samples.;COPYRIGHT: (C)2001,JPO
