Optical Emission Interference lines 1

[bruv]

This may not be the right forum in which to place this question, but I couldn't find a better one, so here goes.

I have an OES, analysing Fe-base, Ni-base and Cu base alloys. I would like to know where to find information (preferably) on-line about interference lines for OES machines.

Many thanks

For a primer on interference arising in emission spectroscopy, see
"Principles of Instrumental Analysis", Skoog & Leary, 4th Ed., 1992, Section 10E-3 (pp 225-227).

(no doubt it will be in newer editions, just under different section numbers).

The other 'generic' advice I offer you is to use google to perform a web search, and contact the manufacturer of your instrument for more specifics regarding interference.

One source that has helped me is the book Wavelength Tables that was published by MIT in 1969. It includes intensities in arc, spark, or discharge tube. I'm not sure if it is even available anymore, but I would be glad to check some wavelengths for you.

What type of OES do you use? I am working on a new calibration and am having some trouble with the Ta lines. Do you have any info regarding this.
