Can free carbon in SiC be rapidly and conveniently quantified?

Lapis lazuli is a deep-blue metamorphic rock used as a semiprecious stone which contains inclusions that can impact its value. Pyrite impurities and major elements distribution are studied with the XGT-9000, HORIBA’s new X-ray microscope.

Talc is used in a wide range of manufactured products. These final products are a mixture of many different components, so the talc is usually measured prior to mixture. Particle size is important to final product surface quality or mechanical strength of the product.

Magnetite is used in various applications from speaker production and high speed disk drives to a color additive in cement.

This application note describes the method and conditions to use with the EMIA 820V C/S analyzer to measure cement.

Depth profile analysis by GDOES. Pulsed RF Glow Discharge Optical Emission Spectrometry offers ultra-fast elemental depth profiling capability for the investigation of thin and thick films. Thanks to the use of a pulsed RF source, coupled with a high resolution optical spectrometer, the GD Profiler 2 provides an excellent depth resolution, allowing the fast evaluation of the coating quality. In this application note, we focus on a MoS2/Pb composite multilayered sample, used as a solid lubricant. The analysis of such a sample shows the excellent performance of this instrument for the study of nm-thick complex coatings.

Traditional sieve measurements are being replaced with automated digital image analysis. Successful incorporation of digital image analysis often includes data correlation to sieve results, followed by realizing the advantages offered by this technique.

The behavior of an abrasive material is influenced by the hardness, size, and shape of the particles. A harder particle will be more aggressive in altering the surface of the work piece. Larger particles generate higher impact force removing the material surface quicker and producing a heavier texture. Particle shape also plays a role.

Pulsed Radio Frequency Glow Discharge-Optical Emission Spectrometry was used to study different electroplated samples. The flexibility of the spot size, the use of a pulsed RF source and the introduction of the differential interferometry profiling make RF GD-OES a key technique for the electroplating industry.

Pulsed RF GDOES is a companion analytical tool for magnetron sputtering deposition. Magnetron sputtering is a type of Plasma Vapour Deposition. The vacuum chamber of the PVD coating machine is filled with an inert gas, such as argon. By applying a high voltage (RF, HIPIMS etc), a glow discharge is created, resulting in acceleration of ions to the target surface and a plasma coating. The argon-ions will eject sputtering materials from the target surface (sputtering), resulting in a sputtered coating layer on the products in front of the target.
