Determination of lanthanum, cerium, neodymium, ytterbium, and yttrium in geological samples with the use of a multichannel analyzer of atomic emission spectra

The procedure of atomic emission determination (with a photographic record of the spectrum) of yttrium and four rare-earth elements (La, Ce, Nd, and Yb) was modified on the basis of a multichannel analyzer of emission spectra (MAES) in geological samples of various contents. In addition to the incre...

Description
Summary:The procedure of atomic emission determination (with a photographic record of the spectrum) of yttrium and four rare-earth elements (La, Ce, Nd, and Yb) was modified on the basis of a multichannel analyzer of emission spectra (MAES) in geological samples of various contents. In addition to the increase in the rate of analysis, the detection limits were improved by a factor of two to three, correct calculation of the background was realized, and the errors of reproducibility of analysis were decreased. The validity of the results was confirmed by the comparison of the contents obtained with the accepted characteristics of the samples analyzed according to GeoPT program and with the data of MS-ICP analysis.
