In the previous report (Journal, Iron and Steel Institute, Japan, XXVII, No.3, pp.184∿190) the modified Orsat gas micro-analysis apparatus for the determination of hydrogen in iron and steel was informed. In the present report, the heating furnace of the steel specimen and the pumping and collecting equipments of the gas from the specimen was described. The quartz tube in which the steel specimen had been placed, was heated by the wire-wound furnace. The gas issued from the specimen was pumped by a threestage mercury diffusion pump of glass and then collected by a mercury drop pump in a collecting vessel. When the gas collection was complete, it was transferred to the gas analysis apparatus for determination.
