Title:
FLOW ANALYSIS DEVICE
Document Type and Number:
Japanese Patent JP3239290
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a quantitative analysis device that can determine alcohol concentration in liquid rapidly and precisely on wash water or the like used in a continuous copper wire material rolling process.
SOLUTION: A flow analysis device has a measuring passage A where a sample solution is made flow by a carrier, a column 1 for eliminating hydrophobic organic content (oil content or the like) contained in the sample solution, and a cleaning passage B for cleaning the column 1. The measuring passage A and cleaning passage B are connected in a freely switched state to the column 1. Determination is performed after adsorption-eliminating the oil content or the like, and after measurement, the passage is switched to clean the column 1.
