US EPA SW-846 Method 6010C Using the Prodigy7 ICP-OES Manuel Almeida, Teledyne Leeman Labs The Teledyne Leeman Lab’s Prodigy7 High-Dispersion ICP instrument is capable of performing analyses according to SW-846 Method 6010C, which is applicable to groundwaters, the Toxicity Characteristic Leaching Procedure and Extraction Procedure, industrial organic wastes, soils, sludge, and sediments. Read More Ultrafine Grinding with Laboratory Ball Mills Kyle James, Verder Scientific, Inc. Nanoparticles are produced by colloidal grinding, which involves dispersion of the particles in liquid to neutralize the surface charges. Factors such as energy input and the size reduction principle make ball mills the best choice for the production of nanoparticles. Read More Trace Elements in Aqueous Solution by EDXRF Scott Fess, Applied Rigaku Technologies Application Note # 1011 describes quantitative analysis of trace amounts of 12 elements using the benchtop Rigaku NEX CG spectrometer in conjunction with the patented UltraCarry® sample preparation technique. Read More PFA Cyclonic Spray Chamber for ICP-OES and ICP-MS Don Potter and Greg Eiden, Savillex An inert cyclonic spray chamber manufactured from molded PFA for use in ICP-OES and ICP-MS instruments offers several design benefits, including enhanced sensitivity, improved draining, and increased wettability with an optional surface treatment. Read More Simultaneous Detection of Surface and Bulk Composition of a Magnesium Alloy Forrest Weesner, TSI Incorporated 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 were collected using the ChemReveal® Desktop LIBS Analyzer. Read More   One Platform Particle Characterization with Static Imaging and Raman Eunah Lee, PhD, HORIBA Scientific Particles retained on a filter during a quality control process were investigated using the ParticleFinder module, which combines static imaging and Raman spectroscopy for both morphological and chemical characterization. Read More Analysis of Artificially Weathered PET and a Separate PET Hydrolysis Evaluation Using the 4300 Handheld FTIR Frank Higgins, Pik Leung Tang, and Alan Rein, Agilent Technologies This application note shows that a handheld infrared spectrometer is effective at measuring early onset chemical changes in environmentally stressed PET polymers that precede cracking and other physical degradation processes. Read More Getting The Best Results from NIR Measurements Frederick Haibach, Owen Wu, Jack Qian, and Eric Bergles, BaySpec, Inc. Obtaining optimal results with NIR spectrometers depends more on a good signal-to-noise ratio and less on high spectral resolution. Read More Detection of Adulteration of Glycerol with Diethylene Glycol by IR Ian Robertson, PerkinElmer There is a significant number of glycerol adulteration cases found by various regulatory services around the world. This application note focuses on fast and accurate verification of samples or to confirm the presence and concentration of the common adulterant diethylene glycol (DEG). Read More
