Molecular High-Precision Reflectivity Measurements of Diffuse Samples To illustrate the accuracy of the External Integrating Sphere, samples with high, medium, and low reflectivity were measured and compared with known values. Process Raman of Solids and Turbid Media We describe how understanding optical scattering properties affects choice of Raman sampling probe to ensure representative sampling in solids and turbid media. Why Are Collimating Lenses So Important? Collimating lenses allow users to align light in their spectrometer setup. In this application note, we explain the importance of collimating lenses in your spectroscopic system. Analysis of Plant Pigments with Raman Spectroscopy Raman spectroscopy is a valuable tool in detecting environmental stress in plants and can show damage before it is visible to the naked eye. Analyze Lithium-Ion Batteries Renishaw’s inVia Raman microscope is the ultimate system for studies ranging from fundamental research to final product QC and failure analysis. Diamond Anti-Reflection Coating Spectral Systems has developed its Diamond XP-BBAR™ coating with spectral performance. The SNR is ~30% better through most of the analysis region of a typical FT-IR instrument.   Atomic Microwave Digestion of Mixed Oils and Polymers This application note demonstrates the performance of the CEM MARS 6 for digestion of large difficult mixed oil and plastics samples in a single run for elemental analysis. Metallurgical: Impurities in Lead Using ICP-OES This work demonstrates the ability of the Avio® 500 ICP-OES to measure impurities in lead to comply with London Metal Exchange requirements. Temperature-Controlled XRD Measurement Measurements from room temperature to 500°C with a desktop system, enabling observation of a phase transition of a substance due to temperature change in real time, is demonstrated. Performance of the DST Acid Purification Systems Savillex acid purification systems provide a continuous supply of high purity acid for metals analysis. User data for both semiconductor and geochemical applications is presented. Analysis of Toxic Elements in Supplements per USP 2232 Using ICP-MS Presented here is an example of a quantitative analysis performed on arsenic, cadmium, mercury, and lead in dietary supplements using ICP-MS. Cement Analysis Using XRF Spectroscopy In this application note, we demonstrate how to analyze various types of cement using XRF spectroscopy, including the milling and pressing of the sample prior to measurement.
