MAY 2008 SPECTROSCOPY GLOBAL EDITION 35 ing wavelength ranges: 380–400 nm (violet), 430–450 nm (blue), 470–490 nm (cyan), 530–560 nm (green), and 630–650 nm (red), with power ranging from 50 to 150 mW (depending on wavelength selected). The first products offered are intended for fluorescence microscopy. A polarization toolbox has been introduced by Olis, Inc. (Bogart, Georgia) as a stand-alone module or as an accessory to its other products. Olis currently offers a fluorimeter, a circular dichroism instrument, and a spectrophotometer. The accessory includes two polarizers, a modulator (photoelastic modulator), and a photon-counting module. The stand-alone module has the same components, but also includes a sample chamber and computer control software–hardware. The stand-alone version also requires the selection of a suitable source, typically an LED, a xenon arc lamp, or a laser. For the past two years, the analysis of biofuels, and especially biodiesel, has been a focus for a number of companies, and analyses ranging from FT-IR, to gas chromatography (GC), ICP emission, and titrimetry have been featured with products offered by a wide range of companies. With analysis methods comes the requirement for measurement standards, and VHG Labs has introduced a range of standards, primarily for metals and sulfur analyses based on B100 (100% fatty acid methyl ester based biodiesel). Finale There were many diverse new products and technologies to cover this year at Pittcon. I am certain that I did not cover everything, and my apologies about the products I might have missed. The show was personally very gratifying because of the new boost in Raman products and the increase in the use of smaller and lower-cost instrumentation. I hope that Raman is now back to stay. Some people might say that never went away, and that is true. But now we can really say that Raman is a mainstream technique and is offered in a broad spectrum (no pun intended) for instrumentation designs and formats. I am anticipating that the trend of smaller instrumentation will continue, and I hope to see that trend continue at Pittcon 2009. References (1) J.P. Coates, Spectroscopy 3(4), 14–19 (1988). (2) J.P.
