ANALYZER FOR SOLUTION SAMPLE

摘要

PURPOSE:To prevent oxidation of iron (II) ion in sample water to iron (III) by air by providing a sample introducing tube consisting of a wall by which the sample water and the air are shielded. CONSTITUTION:A sample is admitted by a sampling tube 1 through a valve 2 and a sample introducing pipe 5 into an analyzer 7 and is discharged through a liquid discharging port 6. The tube 5 consists of double tubes 4, and the air between the inside tube and outside tube is discharged through an air discharging port 3 by a vacuum pump. Then the intrusion of the air into the sample is obviated and therefore the oxidation of iron (II) ion is prevented.
