NOZZLE FOR LIQUID SAMPLE COLLECTION AND METHOD OF MANUFACTURING THE SAME

PROBLEM TO BE SOLVED: To provide a nozzle for liquid sample collection having a nonlinear pipe part where adsorption and sticking of components in a liquid sample on an internal surface are small, and a method of manufacturing the same.SOLUTION: There is provided the nozzle for liquid sample collection which is a metallic nozzle, and includes a nonlinear pipe part 26 in a flow passage 20, and has a noble metal plating layer 12 formed at least on a wall surface of the nonlinear pipe part 26 in the flow passage 20. Further, there is provided the method of manufacturing the nozzle for liquid sample collection including a step of molding the metallic nozzle 10 having the nonlinear pipe part in the flow passage by machining, and a step of forming the noble metal coating layer 12 by electroless plating at least on the wall surface of the nonlinear pipe part 26 in the flow passage 20 of the metallic nozzle.
