Abstract

Transient infrared emission spectroscopy (TIRES) is a new method that produces analytically useful emission spectra from optically thick, solid samples by greatly reducing self-absorption of emitted radiation. The method reduces self-absorption by creating a thin, short-lived, heated layer at the sample surface and collecting the transient emission from this layer. The technique requires no sample preparation and may be applied to both moving and stationary samples. The single-ended, noncontact TIRES measurement geometry is ideal for on-line and other remote-sensing applications. TIRES spectra acquired via a Fourier transform infrared spectrometer on moving samples of coal, plastic, and paint are presented and compared to photoacoustic absorption spectra of these materials. The TIRES and photoacoustic results are in close agreement as predicted by Kirchhoff's law.

Transient infrared emission spectroscopy

Conference McClelland, J; Jones, R

Conventional infrared emission spectroscopy has normally been applied only to optically thin samples because of the phenomenon of self-absorption. In an optically thick material, self-absorption severely alters the emission so that the resulting spectrum closely resembles a black-body emission spectrum. Spectral features characteristic of the material are very weak and grossly altered in appearance, making the spectrum analytically of little use. Transient infrared emission spectroscopy (TIRES) produces useful emission spectra from optically thick samples by greatly reducing self-absorption. In TIRES a laser beam is used to rapidly heat the sample surface creating a transient hot layer. A spectrometer collects themore »« less

Quantitative analysis of solids in motion by transient infrared emission spectroscopy using hot-gas jet excitation

Journal Article Jones, R; McClelland, J - Analytical Chemistry (Washington); (USA)

Quantitative compositional analysis of optically thick solids in motion is demonstrated by using transient infrared emission spectroscopy (TIRES). TIRES greatly reduces the self-absorption that normally degrades conventional emission spectra so that they closely resemble blackbody spectra. Quantitative compositional analyses of poly((methyl methacrylate)-co-(butyl methacrylate)) and poly(ethylene-co-(vinyl acetate)) with standard errors of prediction under 1% were achieved with only a few seconds of data acquisition using principal component regression. Use of a hot-gas jet in place of a laser in the TIRES technique allows study of materials that do not absorb strongly at common laser wavelengths while reducing cost and complexity.

Advanced spectroscopic analysis of coal surfaces during beneficiation

Technical Report McClelland, J; Oh, J

Development work advanced on two new FTIR spectroscopic approaches for measuring coal surface oxidation and on-line infrared spectra of coal. The former FTIR/UV approach used UV induced oxidation to gauge the level of carbonyl forming species present in coal. The latter approach is called Transient Infrared Emission Spectroscopy (TIRES) and uses pulsed surface heating of coal to obtain an emission spectrum which is not distorted by excessive self absorption. In FTIR/UV work oven-oxidized coals were analyzed after 1, 3, and 6 days of exposure to oxygen at 100{degree}C. Spectra of the oven and U induced carbonyl formation overlapped but hadmore »« less

Coupling Pulse Radiolysis with Nanosecond Time-Resolved Step-Scan Fourier Transform Infrared Spectroscopy: Broadband Mid-Infrared Detection of Radiolytically Generated Transients

Journal Article Grills, David; Layne, Bobby; Wishart, James - Applied Spectroscopy

We describe the first implementation of broadband, nanosecond time-resolved step-scan Fourier transform infrared (S ² -FT-IR) spectroscopy at a pulse radiolysis facility. This new technique allows the rapid acquisition of nano- to microsecond time-resolved infrared (TRIR) spectra of transient species generated by pulse radiolysis of liquid samples at a pulsed electron accelerator. Wide regions of the mid-infrared can be probed in a single experiment, which often takes < 20–30 min to complete. It is therefore a powerful method for rapidly locating the IR absorptions of short-lived, radiation-induced species in solution, and for directly monitoring their subsequent reactions.

Transient infrared transmission spectroscopy

Journal Article Jones, R; McClelland, J - Analytical Chemistry (Washington); (USA)

Transient infrared transmission spectroscopy is a new method that can acquire analytically useful transmission spectra from moving, optically thick solids. No sample preparation is required. The spectra are of sufficient quality for accurate quantitative compositional analysis. The method works by the creation of a thin, short-lived, chilled layer at the sample surface. Blackbody-like thermal emission from the bulk of the sample is selectively absorbed as it passes through the chilled layer, so the transmission spectrum of the layer is superimposed on the observed thermal emission. Spectra of polycarbonate, beeswax, and copolymers of methyl and butyl methacrylate are presented. Compositional analysismore »« less
