The historical developments leading up to Maxwell's equations are discussed in Part I of this series.

The revisions to GMP Annex 11 are examined in terms of the impact on computerized spectrometry systems operating in regulated GMP laboratories.

One of the fastest growing new areas of demand for Raman spectroscopy is in the security market. Technological improvements have helped to unlock the large potential of the technique for security applications. There has been a rash of acquisitions in the market that have completely reshaped the competitive landscape over the last few years, which is typical of such dynamic markets.

A general MIC–ICP-MS method has been successfully developed for the assay of elemental impurities in pharmaceutical products.

The wavelet packet transform (WPT) combined with the modified uninformative variable elimination (MUVE) method (WPT–MUVE) is proposed to select variables for multivariate calibration of spectral data.

A Q&A with Jose Almirall, PhD, professor in the Department of Chemistry and Biochemistry and the director of the International Forensic Research Institute at Florida International University.

The growing and evolving use of homemade explosives, as well as biological and chemical threats, in terrorism and modern warfare, has driven the development of new and improved methods for detecting and identifying these materials. University and military researchers, as well as commercial instrument companies, are working hard to develop systems that are portable and rugged enough for field use, particularly for standoff detection.
