Determination of Wear Metals Using Teledyne Leeman Labs Prodigy7 ICP-OES
Manny Almedia, Teledyne Leeman Labs
Wear metals analysis, using inductively coupled plasma-optical emission spectrometetry (ICP-OES), has been an important component of predictive maintenance programs for many years. Used oil-based materials, such as engine oils, transmission oils, and engine coolants, are regularly monitored for the presence of particles deposited from the components that they are designed to protect. These particles gradually build up in the oil due to normal wear of the component. For this reason, the analysis of used oils and coolants is often referred to as wear metals analysis or fluids analysis. This application note will demonstrate the ability of the Teledyne Leeman Labs Prodigy7 ICP to determine a range of elements, both wear and additive, in used oil samples.

Characterizing Electrical Contacts Using the Chemreveal™ LIBS Desktop Elemental Analyzer
TSI Inc.
Connectors and tracks on printed circuit boards supply power and pass signals between electronic components soldered to the board. While primarily made of copper, alloying agents and overcoating are frequently used to improve the manufacturability and durability of traces and contact points. This note reports on analysis metals contacts on an intact circuit board using LIBS. In a single analysis, we obtain information on noble and transition metals as well as beryllium in copper.

Analysis of Antibody Aggregates Using High Mass MALDI-TOF Mass Spectrometry
Shimadzu
Antibody aggregation remains a complex question to address in the development and manufacture of therapeutic antibodies and biosimilars. This note illustrates the ability to characterize antibody aggregates by covalently stabilizing them with cross-linking reagents, fractionating the cross-linked aggregates by SEC, and finally analyzing the fractions using the MALDI-TOF mass spectrometry.

Spectroscopic Characterization of Nanoparticles for Potential Drug Discovery
Shimadzu
The inertness and biocompatibility of gold nanoparticles (Au-NPs) make them very promising for specific applications such as medical imaging, drug delivery, gene delivery, and molecular sensing. This study evaluates the use of spectroscopic techniques, such as UV-vis and FT-IR, to monitor and characterize gold nanoparticles and gold nanoparticle conjugated systems.

Raman Spectroscopy Applied to Lithium-Ion Battery Analysis
Renata Lewandowska, Miyoko Okada, and Tomoko Numata, Horiba Scientific
Raman spectroscopy can analyze cathodes and anodes in Li-ion batteries during the charging and discharging process. As lithium ions travel from one electrode to the other, fast and contactless Raman spectroscopy shows real-time structural changes.

Reflection of Aluminum Alloys for Automotive Wheels
Rob Morris, Ocean Optics
In this application note, we evaluated a color shift that occurred with deposition of a thin film of aluminum chrome alloy to a cured, powder-coated wheel. The alloy had been applied to the wheel surface via direct current (DC) sputtering, a deposition process used to coat surfaces with different materials. The objective of the experiment was to investigate the color shift as a function of deposition time, both before and after clear coating with an acrylic powder for UV protection.

Minerals and Stones — Characterization by FT-Raman Spectroscopy
Bruker Optics
Minerals are mostly inorganic crystalline compounds with a defined chemical structure formed by processes on the earth, moon, or other celestial objects. In contrast to minerals, stones are heterogeneous compounds composed of mineral aggregates. The spectral information in a single Raman spectrum is complementary to that which can be derived from mid and far infrared (MIR and FIR) FT-IR spectra.
