PURPOSE: A sequential injection analyzer is provided to easily exchange a fluid pipeline module, and to move or transport the analyzer with a simple and small structure compare to a conventional analyzer. CONSTITUTION: A sequential injection analyzer comprises the following: a detachable fluid pipeline module(260); and a syringe pump and a multiport valve fixed to a manifold(261), the fluid pipeline module is a laminating structure including substrates with minute flow paths. The fluid pipeline module performs a sequential injection analysis while pressured and coupled to the manifold. The detachable fluid pipeline module is formed with glass, silicon, polymethylmethacrylate, polycarbonate, polystyrene resins and others. A base substrate is connected with the manifold while including a penetration hole.
