RADIOACTIVITY ANALYSIS SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a radiation analysis system having high analysis accuracy and capable of preventing both disturbances in the concentration of components in a test liquid in a retention tube and the equalization of concentration due to the diffusion of the components in a radio-liquid chromatograph of a type interlocked with a liquid chromatograph having the retention tube. SOLUTION: In the radio-liquid chromatograph having the retention tube, an effluent from a column of the liquid chromatograph is made to temporarily stay in the retention tube to partition the staying liquid in the radiation analysis system. The liquid can be partitioned by gas. The gas for partitioning can be injected from a gas syringe provided in front of the retention tube. A sensor for detecting the liquid and the gas in the retention tube can be provided in front of the radiation measuring system. COPYRIGHT: (C)2006,JPO&NCIPI
