Recent Advances in Pharmaceutical Analysis Using Transmission Raman SpectroscopyThis article reviews recent advances in the application of Transmission Raman Spectroscopy (TRS) to pharmaceutical analysis. The TRS technique overcomes subsampling limitations of conventional Raman spectroscopy and enables rapid non-invasive volumetric analysis of intact pharmaceutical tablets and capsules in a quantitative manner with relevance to quality and process control applications. Although only recently introduced to this area its uptake and the breadth of applications are rapidly growing with regulatory approvals for use of this technology in quality control of manufactured pharmaceutical products recently being granted.

Failure Analysis of Packaging MaterialsThe LUMOS FT-IR microscope is an all-in-one solution with an integrated spectrometer, a high degree of automation, and a dedicated user interface. The innovative motorized attenuated total reflectance (ATR) crystal allows performing the complete measurement procedure fully automated including background and sample measurements. The dedicated OPUS software Wizard guides the user through the whole measurement procedure. For identification of unknown compounds, spectrum search and mixture analysis are applied using the functionality of the OPUS/SEARCH package. Chemical images of the spectral data are generated from univariate and multivariate analysis results.

Thickness Analysis of a Natural Oxide Film on a Microscopic Si PatternThe MSV-5000 series micro-spectrophotometer is designed to obtain transmission/reflection measurements over a wide wavelength range from the ultraviolet to the near-infrared wavelengths. It allows the measurement of an area as small as 10 µm diameter and the integrated high-resolution CCD video camera enables visual observation of the samples to determine the precise area to be measured. This instrument is suitable for measurement of micro samples or samples with microstructural features.
