Abstract
A flow analysis system or flow injection analysis system, providing a high detection sensitivity even when metallic elements contained in a sample are of extreme trace in amount, wherein a sealed vessel in which a reagent solution is encapsulated is composed of a material having an oxygen permeability of 10 fmol/m2.s.Pa (2 cc/m2.d.atm) or less.
Claims4
A sealed vessel which is composed of a material having an oxygen permeability of 10 fmol/m2.s.Pa (2 cc/m2.d.atm) or less and in which a solution, containing a color producing reagent which produces colors by an oxidative reaction, is encapsulated, and wherein oxygen content in the solution is 5 ppm or less.
