| Abstract: | A method for the determination of hydrogen in zinc-aluminum by pulse heating-thermal conductivity method was studied.The sample volume,sampling way and heating releasing hydrogen power were investigated.The optimal detection conditions were determined: sampling weight was 2.0-4.0 g,surface hydrogen heating power was 850-900 W and the volume hydrogen heating power was 1 250-1 350 W.The relative stabdard deviation of actual sample determination results was less than 6%(n=9).The reference materials GBW(E) 0200... |
