Columnists Howard Mark and Jerome Workman, Jr. take a final look at the topic of principal components, which has been the subject of six previous installments.

The authors discuss the use of Raman spectroscopy to identify an unknown gem or mineral sample or to verify that a known sample has been classified correctly.

Guest columnist Steven Wilbur discusses the elemental nature of ICP-MS and its strength as a universal quantifier, an aspect of the technique he believes has not received enough attention.

The trickling down of technology and heavy competition are contributing to a strong market outlook for the area.
