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.

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

Spectroscopy previews the annual SPIE Defense, Security, and Sensing Conference, taking place April 5-9, 2010, in Orlando, Florida.

The authors present a comprehensive study of MALDI spotting, based upon the most commonly used dried droplet method, for various peptides of different molecular weight and concentration.

February has arrived and this frigid time of year can mean only one thing in the field of spectroscopy and analytical chemistry in general: it's time for Pittcon.

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.

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.

One of the last frontiers of molecular spectroscopy is in the terahertz region, for which instrumentation has only been developed within the past decade.
