PURPOSE:To reduce the temperature difference between the liquid in an electrode and a sample to be measured and reduce the error of a measured value without deteriorating the processing ability of an analyzing device by installing a preheating mechanism part in front of a detector and devising the sequence control over sample introduction. CONSTITUTION:This analyzing device consists of a sample suction pipe 1, preheating coil 2, Na electrode 3, K electrode 4, Cl electrode 5, reference electrode 6, solenoid valve 7, liquid feed pump 8, drain 9, and thermost 10 of a measurement part. Said preheating coil 2 is formed by forming a metallic pipe with high heat conductivity, etc., in a coil shape, and the area of contacting of the thermost 10 with air and a sucked sample is increased to hold the sucked sample in a balanced state of 37 deg. in a short time. Then, the sample is sucked in twice separately to eliminate the temperature difference between the sucked sample and the liquid in electrodes 3-6 as measurement points. Thus, the simple preheating part is added and the sample suction sequence is devised to reduce the temperature difference between the liquid in the electrodes and sucked sample, thereby taking an analysis with a reduced measurement error without deteriorating the processing ability. |
