Mass Spectrometry

This article discusses the key components of a typical liquid sample introduction system for inductively coupled plasma spectroscopy, and offers troubleshooting tips for problems commonly encountered by practitioners.

Through symposia, posters, and workshops, representatives from industry and academia addressed a broad range of technology and implementation issues that are beginning to change the landscape of modern spectroscopy.

The authors at how linearity considerations fit into the broader scheme of calibration theory, and discuss methods for testing data for non-linearity.

This paper describes how analysts at an environmental and geochemical laboratory utilize dynamic reaction cell ICP-MS technology to study the transport and deposition of important trace metals from rainwater.

The author provides a brief historical and technological review of different types of telescopes, and how they were developed and improved.

This article summarizes recent efforts by the Duquesne University Center for Pharmaceutical Technology to develop and validate a PAT method using NIR spectroscopy for the on-line prediction of tablet hardness and active pharmaceutical ingredient content.

Recent advances in thin-film filter technology have enabled dramatic improvements in the performance of filters for laser-based analytical instrumentation.

The authors show that high resolution 1H nuclear magnetic resonance (NMR) spectroscopy can be used to study biofilm metabolism under environmentally relevant conditions in a minimally invasive way.

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.
