The 2014 FACSS-SciX Interview Series
Understanding Biological Systems at the Quantum Level Using 2D Electronic Spectroscopy
Spectroscopy recently spoke to Greg S. Engel, who is an Associate Professor in the Department of Chemistry at the University of Chicago in Chicago, Illinois, and one of the winners of the 2013 FACSS Innovation Awards. Here, Engel discusses his research examining quantum dynamics in biology, chirality in dynamics, and the use of two-dimensional electronic spectroscopy. MORE »
Increase Accuracy of FT-IR Analysis
DOWNLOAD WHITE PAPER demonstrating the inconsistency in background levels of water and CO2 for an unpurged, sealed, and desiccated FT-IR spectrometer as compared to a sealed and desiccated FT-IR spectrometer with the sample compartment purged. The purge enhances instrument reliability by reducing the need for maintenance and increases the accuracy of analysis by eliminating inconsistencies in background levels of CO2 and water.

Practical Group Theory and Raman Spectroscopy, Part I: Normal Vibrational Modes
Group theory is an important component for understanding the fundamentals of vibrational spectroscopy. The molecular or solid state symmetry of a material in conjunction with group theory form the basis of the selection rules for infrared absorption and Raman scattering. Here we investigate, in a two-part series, the application of group theory for practical use in laboratory vibrational spectroscopy. MORE »

Units of Measure in Spectroscopy, Part I: It's the Volume, Folks!
The data show that different units of measurement have different relationships to the spectral values, for reasons having nothing to do with the spectroscopy. This finding disproves the unstated, but near-universal, assumption that different measures of concentration are equivalent except, perhaps, for a constant scaling factor. MORE »

From the Bench to the Bedside: Infrared Spectroscopy and the Diagnosis and Treatment of Dry Eye and Cataracts
The focus of this review is the application of infrared (IR) spectroscopy to study human lens and tear lipids with minimal discussion of the role of lipids and the complex etiology of cataracts and dry eye. The power of IR spectroscopy to measure composition, conformation, structure, and environment of biomolecules was applied to diagnose cataracts and dry eye and follow the efficacy of treatment. Principal component analysis and other standard algorithms were used to analyze IR spectra. MORE »

NIR Model Transfer Based on Wavelet Transform Algorithms
Methods based on wavelet transform such as denoising, compression, and multiscale analysis were developed for near infrared (NIR) analysis model transfer of an amine mixture to improve the precision of piecewise direct standardization (PDS). Transfer samples and correlative parameters based on wavelet denoising and piecewise direct standardization (WDPDS), wavelet compression and piecewise direct standardization (WCPDS), and wavelet multiscale and piecewise direct standardization (WMPDS) were studied, and the optimal conditions were confirmed.

Raise Your Expectations; Learn How the New Agilent 7900 ICP-MS Redefines ICP-MS Performance
Wednesday, February 26, 2014
11:00 AM EST/ 4:00 PM GMT/ 5:00 PM CET
Metals labs that use ICP-MS have always had to accept the limitations — limited tolerance to high dissolved solids, and a dynamic range that can't reach the major elements. No longer! With the new Agilent 7900 ICP-MS, very high total dissolved samples matrices (e.g., 25% NaCl brine) can be measured routinely, and major elements at % concentration levels can be quantified in the same run as ppt-level traces.
