Differentiation Between Origins of Extra Virgin Olive Oils by GC-C-IRMS Using Principal Component Analysis, Linear Discriminant Analysis, and Hierarchical Cluster Analysis

Spectroscopy - February 1, 2010

The authors classify extra virgin olive oils from Portugal and Turkey using GC-C-IRMS to evaluate the isotope ratios of the fatty acid methyl esters (FAMEs) extracted from the oils.

Analysis of Lignin and Cellulose in Biological Energy Sources by Raman Microscopy

Spectroscopy - February 1, 2010

Cellulosic feedstocks from biological harvests (such as timber, prairie grass, and corn stover) or industrial–urban waste have been proposed as a source for the production of energy in the form of fermentation-produced ethanol biofuel.

Statistics and Chemometrics for Clinical Data Reporting, Part III: Using Excel for Data Plotting

Spectroscopy - February 1, 2010

This installment of "Chemometrics in Spectroscopy" illustrates the various graphical ways used to observe and interpret comparative clinical quantitative measurement methods.

Assessing Accuracy

Spectroscopy - February 1, 2010

In a previous article, we discussed the steps in the chemical analysis process (sample taking, sample preparation, analysis, and results) and promised a follow-up on the question of the accuracy of the results. This article examines systematic error and quantitative analysis.
