“…In addition, the line intensities rise to a constant value in a very short time, so that little presparking is needed before the exposure is started. Boyd and Goldblatt (35) have reviewed some applications of spark excitation in controlled atmospheres.…”

This review, the ninth in a series, covers optical emission spectrometry, flame photometry, and atomic absorption spectrometry for the years 1964 and 1965. In the previous review (280), it was estimated that the 565 references cited represented about one quarter of the publications which appeared in the years 1962 and 1963 within the subject range of these reviews. It appears that a similarly comprehensive coverage for the period of the present review would require approximately 800 references!

“…More recently, use of controlled atmospheres in spark excitation showed improved precision and accuracy, higher sensitivity, and reduced inter-element effects (10,11). Laser-induced plasmas and the effects of ambient conditions on them have been studied extensively.…”

Tables I and II demonstrate the precision of the instrument when used as a routine analytical device. During these analyses, the samples were de-greased in acetone, and the samples were allowed to accumulate in the furnace chamber until all eight samples were analyzed. Samples from a given specimen were analyzed on two different days in order to demonstrate the stability of the instrument. CONCLUSIONSThe instrument described in this article has been satisfactory for the determination of hydrogen in metals over the concentration range from 0.01 wppm to 100 wppm with a precision of 10%. Diffusion parameters, surface reactions, and the distribution of hydrogen in the sample can be evaluated using the hydrogen evolution rate data and the thermal history of the sample after it is dropped into the furnace.Micromole quantities of other gases can also be determined; thus, the instrument can be used to study a great variety of thermally activated gas evolution processes.
