Application Notes

Peak emission for silicon occurs at values beyond the range of sensitivity for silicon-based detectors, like CCDs. EMCCDs combine a larger field of view and higher resolution with high sensitivity in the NIR at lower cost.

Spectral Systems has developed its Diamond XP-BBAR™coating with spectral performance.The SNR is about 30% better through most of the analysis region of a typical FT-IR instrument. www.spectral-systems.com

Olive oil is among the most commonly adulterated food products. Raman spectroscopy has the potential to be utilized in measurements of olive oil to establish purity from adulteration with other, less expensive, oils. This application note reviews some of the most compelling data present in recent scientific literature to support this claim.

The drying of a pressure-sensitive polymer adhesive was monitored by attenuated total internal reflection (ATR) IR spectroscopy. Correlational analysis revealed changes in the composition of the film surface with time.

Handheld Raman is a useful tool for differentiating solvents used in chemical and pharmaceutical manufacturing. This application work describes the application of handheld Raman for identification and confirmation of solvents using an advanced sampling method.

The value of milk and high market demand, has resulted in milk as a target of adulteration. Adulterants intentionally or accidentally added to milk can be detected though the use of NIR Spectroscopy coupled with Adulterant Screen™.

The use of Fourier Transform Near-Infrared Spectroscopy is a rapid and effective technique for determining if spices of high-value products are being adulterated with lower-value commodities.

A broadband polarizing beamsplitter (PBS) cube was developed using embedded Moxtek® Nanowire® grid polarizer technology. The Moxtek ICE Cube™ PBS provides superior performance in broadband, low f/# spectroscopic applications where both high efficiency and excellent contrast are required.

Raman confocal spectroscopy is increasingly being applied for the analysis of embedded contaminants within materials. A non-contact, non-destructive analysis method, Raman spectroscopy requires very little sample preparation, has greater spatial resolution compared to FT-IR microscopy and the confocal analysis method allows visualization of materials within a clear sample matrix. This paper will investigate the analysis of an embedded contaminant within a polymer matrix on a glass substrate.

In this note, we examine a magnesium alloy plate to determine the type of anti?corrosion coating present. In the same experiment, the chemistry of the bulk magnesium alloy can also be observed. All data was collected using the ChemReveal® Desktop LIBS Analyzer.
