Howard Mark and Jerry Workman revisit their recent series on derivatives, marking their 100th column contribution to Spectroscopy.

As part of dyslexia study, Wake Forest University researchers develop a software program that integrates data from different imaging modalities.

Mass 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.

Part 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.

A relatively new technique with a growing number of applications, dichroism spectroscopy is based upon the fact that a sample interacts with the same wavelength of light having different circular polarization in different ways.

The 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.

Part IV of the series describes the use of confidence limits in data analysis for calculating slope and intercept.

The 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.

Raman 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.

Mississippi State University's DIAL Lab has developed a sensor that uses cavity ringdown spectroscopy to noninvasively screen for the disease.

This book covers most of the popular atomic spectroscopy methods used for the determination of the elemental composition of materials.

When considering accurate mass and greater resolution, which mass spectrometer provides the information needed at the best purchase price and with the most accessible operational prospects?

Part IX of the series discusses backup and recovery, which are essential to the process of ensuring data security and integrity.

Once thought to be unnecessary, Brookhaven Laboratory's Mini-Raman Lidar System now serves homeland security and military purposes.

The authors show that dynamic reaction cell ICP MS can eliminate a number of argon- and carbon-based polyatomic interferences, allowing the determination of many critical elements in problematic organic compounds found in the semiconductor industry.

A variable filter array spectrometer can help defeat the environmental restraints of traditional infrared spectrometers.
