Mass Spectrometry

The author previews the 13th annual Winter Plasma Spectrochemistry conference.

Near-infrared spectroscopy moves into warehouses to check incoming drug substances, excipients, and packaging materials, and onto the production floor to monitor characteristics such as blend uniformity, moisture content, and dissolution rate.

The author discusses the process analytical technologies initiative and its effect on spectroscopy.

Infrared technology was used as a method for rapid detection of potential Severe Acute Respiratory Syndrome.

Trace-level detection of explosives using spectrometric techniques.

The author discusses how to identify some of the performance qualification tests to apply to spectrometry software, how to write the test procedures and instructions, and how to execute the actual testing.

This article provides a brief overview of some of the latest spectroscopy-related equipment and supplies scheduled to be introduced at the 2003 Denver X-ray Conference at the Denver Marriott Tech Center Hotel in Denver, Colorado, August 4?8, 2003.

The x-ray energy spectrum provides rapid identification of mineral samples.

Oregon Health and Science University (OHSU, Portland) has proposed a research and academic program in chemical biology in which chemists and biologists work next to each other, in the same facility, on drug discovery projects.

This first installment in a series about challenges and pitfalls in interpreting data from hyphenated techniques explores general concepts in initial approaches.

The author discusses an alternative to filament sources when working with electron ionization.

The authors discuss the use of serial coulometric flow cells coupled online with electrospray ionization mass spectrometry in predictive assays for absorption, distribution, metabolism, excretion, toxicity (ADME/Tox), and stability implemented at early stages of drug discovery.

The authors investigated the analytical capabilities of three types of mass analyzers for liquid chromatography-mass spectrometry (LC-MS) applications, studying the effects of instrument parameters and issues related to sample preparation on the performance of LC-MS analytical methods.

This article focuses on units in mass spectrometry, with commentary on history and usage, as well as common debates.

The staff members of Spectroscopy and LCGC North America present information about some of the latest mass spectrometry instruments, accessories, and supplies.

The third installment in a four-part series on chemical noise in mass spectrometry discusses examples of chemical ionization and fast atom bombardment in conjunction with MS/MS.

Spectroscopy?s annual overview presents new instrumentation that was introduced at the Pittsburgh Conference and Exposition on Analytical Chemistry and Applied Spectroscopy (PittCon), held this year March 10?13 in Orlando, Florida.

Often, mass spectra of compounds found in water supplies are not found in mass spectral libraries. Ion composition elucidation (ICE) provides the elemental compositions of the ions observed in their mass spectra. This information is used to identify the compounds.

Laser-induced breakdown spectroscopy helps to detect explosives, chemical agents, and bioweapons.

A fiber-optic, mid-IR spectroscopy probe combined with a grazing-angle reflectance sampling head can be used as a solvent-free, in situ method for validating cleanliness with substantial improvement in accuracy, compared with traditional methods.
