Determination of carbon, nitrogen, and oxygen in solids by laser mass spectrometry

Carbon, nitrogen and oxygen are measured directly in Fe and plain C steel metal specimens without standards by laser mass spectrometry. Accuracy is within the uncertainty of NBS standard reference materials used to test the technique. The results indicate that parts ppb level measurements of these e...

Description
Summary:Carbon, nitrogen and oxygen are measured directly in Fe and plain C steel metal specimens without standards by laser mass spectrometry. Accuracy is within the uncertainty of NBS standard reference materials used to test the technique. The results indicate that parts ppb level measurements of these elements will be straightforward. Contributions due to interactions of samples and residual gases are negated by increased rates of laser cleaning in relationship to the background gas pressure.--AA
