In order to overcome the difficulty in hydrogen analysis under high pressure surrounding gas, a new technique was developed. In this technique, we used He metastable states produced in a high pressure He gas breakdown plasma to excite hydrogen atom. It was found that the TEA CO_2 laser was favorable for inducing overwhelming He metastale excited state with the help of a metal target. This technique can be used for gas and metal analysis, while for non metal solid analysis, a metal mesh was placed above the sample surface to initiate the He gas breakdown plasma and the ablated atoms from the sample were sent into the He gas breakdown plasma region to be excited effectively through the He metastable atoms.
