まり点計におけるサンプル液の吸引機構。[Scope of Claim for Utility Model Registration] In a sample liquid suction mechanism in a clogging point meter that sucks the sample liquid from the analysis section through a filter at a predetermined suction pressure and detects the sample liquid passing through the filter, (a) A low-volatility liquid is injected into a sealed tank so that a space is formed in the upper part of the tank, and one end of the air inflow pipe is open to the atmosphere, and the other end of the air inlet pipe passes through the wall of the tank in an airtight manner. (b) an air suction device communication pipe having one end connected to the air suction device and the other end communicating with a space in the sealed tank; (c) an analysis unit communication pipe having one end communicating with the space in the sealed tank and the other end connected to the analysis unit, and applying negative pressure to the space in the sealed tank by operating an air suction device. When generating this negative pressure and transmitting this negative pressure as suction pressure to the analysis section via the analysis section communication tube, the insertion length of the air inflow tube into the liquid is formed to a length corresponding to the required suction pressure. Suction of sample liquid in a clogging point meter, characterized in that air outside the tank is introduced into the tank through the air inflow pipe when the negative pressure inside the tank becomes greater than the required suction pressure. mechanism.
