Quantitative Analysis of Shales by KBr-FTIR and Micro-FTIR

Fuel, 2014
Abstract Fine-grained texture, complex mineralogical composition, and diverse organic matter types cause large heterogeneity of shale, and the resulting analytical challenge can only be met with high-resolution techniques. Quantitative determination of clay minerals, quartz and carbonates, as well as organic matter in shale on a micrometer-scale is ...

A unified approach to the chromatography‐FTIR interface: GC‐FTIR, SFC‐FTIR, and HPLC‐FTIR with subnanogram detection limits

Journal of High Resolution Chromatography, 1991
AbstractThe results described in this paper demonstrate that Identifiable FTIR spectra of components separated by gas, supercritical fluid, and liquid chromatography can be measured in real time using a common approach. The sensitivity of each Interface is comparable with that obtained by interfacing the corresponding technique with a bench‐top mass ...

FTIR And TGA/FTIR Characterization Of A Polyethylene Photodegradable Concentrate

SPIE Proceedings, 1989
An integrated thermogravimetric/Fourier transform infrared (TGA/FTIR) system is used to detect the presence of a fatty acid in a commercial, photodegradable, polyethylene concentrate. This technique is simple, rapid, convenient, and requires minimal sample manipulation. It can be very useful for monitoring the differences in resin concentrates. Results
