Here are the top five articles that the editors of Spectroscopy published this week.
Masses in Mass Spectrometry: Balancing the Analytical Scales (PDF)
November 1st 2004Mass spectrometrists have been measuring masses in the ultrasmall world for the past 50 years. However, a sense of our own accomplishments does not derive from the same perspective linking ultrasmall masses to the normal-mass world.
Depth Profiling with Confocal Raman Microscopy, Part II (PDF)
November 1st 2004Part II of the two-part series continues the discussion on the interpretation of confocal Raman data, including how depth resolution is degraded when focusing deep within a sample and how intensity variations can occur when focusing near a sample's surface.
Strategies for Higher Throughput MS Analyses (PDF)
November 1st 2004The authors discuss current approaches for increasing throughput in MS analyses, including improved software information flow, data management and effective sample preparation, and how researchers should consider each of these with regard to their own needs.
Fast Multidimensional NMR Spectroscopy by the Projection-Reconstruction Technique (PDF)
October 1st 2004The authors describe a new method for making faster measurements of multidimensional NMR spectra. The technique involves acquiring a small number of projections and using them to reconstruct the entire spectrum.
Depth Profiling With Confocal Raman Microscopy, Part I (PDF)
October 1st 2004Raman microscopy is one of the techniques of choice for investigating heterogeneous systems on the micrometer scale. Part I of this two-part article series reviews the issues that must be considered to interpret confocal Raman data correctly.
FT-IR Spectroscopy: An Advanced Tool for Studying Biomedical Problems (PDF)
July 1st 2004The authors describe several applications of FT-IR spectroscopy in the biomedical sciences, including characterization of healthy and neoplastic human skin samples affected by two kinds of cancers, and examination of liver damage and regeneration caused by carbon tetrachloride.
Powerful Partners Provide Complete Analytical Solutions (PDF)
June 2nd 2004This article examines advances that have been made to combine existing analytical techniques with Raman instrumentation. Some of these methods offer enhanced sample visualization, while others provide complementary vibrational spectroscopic information from a single sample point.
Raman Microscopy as a Valuable Tool for Failure Analysis (PDF)
June 2nd 2004The authors discuss several sample types encountered in their laboratory for which Raman spectroscopy is the only reliable method of analysis. The technique is shown to be a routine and cost-effective tool for the industrial laboratory.
Raman Spectroscopy for Homeland Defense Applications (PDF)
June 2nd 2004Raman spectroscopy is used routinely by the agencies tasked with homeland defense, and current research using surface enhanced Raman spectroscopy shows promise for the detection of chemical warfare agents and other toxic chemicals. This article overviews some of the latest developments in the field.
Recent Advances in Bioanalytical Mass Spectrometry and Their Application to Marine Toxins (PDF)
June 1st 2004The analytical challenges in marine chemistry are numerous due to the large number of natural toxins and their metabolites, the highly toxic nature of many of these compounds, and increasingly stringent regulatory guidelines. This article gives an overview of some recently developed mass spectrometry techniques and their application to marine biotoxins.
