<p><P>PROBLEM TO BE SOLVED: To provide a structure of reaction part for a trihalomethanes analyzer, capable of restraining heat from being transferred from a reaction part side to a separation/dissolution part side, so as to prevent performance from getting worse caused by overheating in a separation/dissolution part constitutive member, and capable of reducing an analyzer cost by making the structure of a reaction part and a separation/dissolution part, simple and compact. <P>SOLUTION: The structure includes the reaction part 36 for heating a trihalomethanes dissolved carrier solution from the separation/dissolution part 38 for separating tri-halo-methane gas from a water sample and for dissolved it into a carrier liquid, and for bringing the trihalomethanes into reaction with a nicotinamide, and the reaction part 36 includes a tube 31 having a flare-shaped terminal, a plane 30 with a groove formed with the groove 30s capable of embedding continuously the tube 31, and having a hole 30t drilled to draw out a flare-shaped portion of the tube 31 to an outside, and a reaction part presser bar 32 having a flat part brought into close contact with a flat face of the plane 30 with the groove. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
