Document Type and Number:

Japanese Patent JP3758585

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To introduce a specimen by putting one specimen introducing device to common use with respect to a plurality of channels of analysis flow paths.
SOLUTION: This system has two channels of analysis flow paths A and B, comprising liquid feeding parts A and B, specimen introducing devices A and B, columns A and B, and detectors A and B, these being connected by flow paths in order. The introducing device 1 is inserted between the feeding part A and the column A of one flow path A by means of a two-position six- way valve 2, thereby forming a first flow path (1) in which the feeding part A, the valve 2, the introducing device 1, the valve 2, the column A, and the detector A are connected in order. In the other flow path B, the feeding part B is directly connected to the column B by means of the valve 2, and a second flow path (2) is formed by connecting the feeding part B, the valve 2, the column B, and the detector B, in order. By changing over the valve 2, changeover takes place between access destinations of the first and second flow paths (1) and (2), that is, between the flow paths A and B connected to the introducing device 1.
