Spectroscopy Application Note Alert Having trouble viewing this email? Click here Atomic Simplifying Mixed-Food Microwave Sample Preparation for ICP-MS Analysis Single Reaction Chamber technology is used to simplify and optimize food and mixed-food microwave sample preparation for trace metal analysis using ICP-MS. Speciated Arsenic Analysis in Wine This application note demonstrated the validation of an extended FDA Elemental Analysis Manual method. The method was optimized for the analysis of four arsenic species.   Molecular Quantifying Protein Concentration Using UV Absorbance In this application note, we examine how a UV absorbance technique can be used to quantify the amount of protein in a sample. Raman ID of Ultramarine Blue Pigment A TSI ChemLogix EZRaman-I instrument, used with TSI’s software offering, SpectraGryph, eases the identification of ultramarine blue, a historically important pigment. LOD in Fluorescence: Compact Spectrometers Compact spectroscopy now has the sensitivity and speed to compete with benchtop fluorimeters. Here we demonstrate picomolar limit of detection for fluorescein in 50 ms. Automated Specular Measurements of a Thin Film Using an automated sampling accessory, the specular reflectivity of a thin film was characterized. Benefits of automation, such as spectral optimization, are discussed. Have I Selected the Right Laser for My Raman Experiments? In this white paper, we discuss important performance parameters to consider when selecting the laser for Raman spectroscopy experiments. Identifying Synthetic Polymer and Rubber Contaminants Here we demonstrate how the Agilent Cary 620 FTIR microscope and imaging system can identify defects and monitor compositional variability in a synthetic polymer. Identification of Counterfeit Phosphodiesterase Inhibitors Using NIR and Chemometrics The use of chemometric models using the Spectrum Two N FT-NIR with AssureID and Spectrum 10 software to determine the authenticity of sildenafil, tadalafil and vardenafil tablets Quality and Process Control of Natural and Processed Iron Ores by Pressed Powder Method An improved method to determine total iron in iron ores by pressed powder method using a multi-channel system
