Non-Destructive Evaluation of Composite Thermal Damage with Agilent's New Handheld 4300 Handheld FTIR
Frank Higgins, Agilent Technologies
The increasing use of composites to replace metal components demands more sophisticated diagnostic tools to detect problem and confirm chemical composition of the material. In this application note, we demonstrate that the 4300 Handheld FTIR is an ideal tool for the task, allowing users to effectively measure thermal overexposure and damage in carbon fiber composites at-site without destroying the sample.

Effect of Sandblasting on the Specular Reflection from Encoder Wheels
Yvette Mattley, Ocean Optics
Spectral reflectance measurements can compare objects of different colors and textures. In this application note, we showed the results of reflectivity of both metal and plastic encoder wheels before and after sandblasting. Sandblasting is often part of the process of preparing machined parts, and in this case may have been used to lessen the specular reflection of the metal and plastic materials.

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.

Predicting % Ash Content in Coal
Applied Rigaku Technologies
Rigaku EDXRF application note #1378 demonstrates the effectiveness of energy dispersive X-ray fluorescence (EDXRF) spectrometry for predicting the amount of ash content in coal before it is burned. The analysis is simple, with the prospective ash material expressed as a percentage of the original weight. The performance described demonstrates the ability of the NEX QC analyzer to yield excellent results for the analysis.
