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.

Determination of Contaminants in Wine Using an ICP-MS TechniqueStrict and steady food control protects consumers against undesired contaminations and guarantees a high level of quality. This can be achieved by enforcing maximum allowable concentrations of hazardous substances. For simultaneous quantitative determination of the inorganic elements in wine, the ICP-MS technique is the preferred quality control tool. ICP-MS offers high sensitivity (trace detection), a wide dynamic range and a high sample throughput. In this study, commercially available red and white wines were investigated; 14 different elements were quantified simultaneously: arsenic, cadmium, caesium, copper, chromium, vanadium, iron, manganese, nickel, lead, selenium, tin, thallium and zinc. The developed ICP-MS method has a high accuracy, regardless of element concentration.

FT-IR Microscopic Analysis of Polymer Laminate Samples Including Transmission and ATR SpectroscopyPolymer laminates typically make complex samples for infrared analysis, comprising multiple layers with defined thicknesses, in some cases less than 10 µm. When measuring extremely narrow laminate layers, the use of attenuated total reflectance (ATR) may provide improved spectra of the laminate cross-section, because ATR microscope objectives offer a greater spatial resolution than transmission due to additional magnification. This paper details the preparation of polymer laminate sample cross-sections and the collection of transmission and ATR spectra of various layers. Further analysis of the laminate spectra will also be explored utilizing a multivariate curve resolution (MCR) algorithm. An example laminate sample is examined utilizing all the tools available on a standard FT-IR microscope.
