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.

Raman Spectroscopic Detection of Olive Oil Adulteration
Dr. Amy Bauer, TSI Incorporated
Olive oil is among the most commonly adulterated food products. Raman spectroscopy has the potential to be utilized in measurements of olive oil to establish purity from adulteration with other, less expensive, oils. This application note reviews some of the most compelling data present in recent scientific literature to support this claim.
