PROBLEM TO BE SOLVED: To provide a hydrogen sulfide removal filter for gas analysis capable of determining a lifetime surely even when a shading container is used.SOLUTION: A hydrogen sulfide removal filter for gas analysis is constituted as follows. A granular material 7 containing a silver salt is stored in a cylindrical container 1 in which at least a shell part 2 has shading property, and a gas inflow port 3 is formed on one end and a gas outflow port 4 is formed on the other end, and an agent discoloring by being reacted with hydrogen sulfide is impregnated into a particle push plate 6 arranged at least on the gas outflow port 4. |
