Ethylene - NIST

Notice: Except where noted, spectra from this collection were measured on dispersive instruments, often in carefully selected solvents, and hence may differ in detail from measurements on FTIR instruments or in other chemical environments. More information on the manner in which spectra in this collection were collected can be found here. Notice: Concentration information is not available for ...

Analysis of Slag Chemistry by FTIR‐RAS and Raman ...

03-10-2014 · Based on the FTIR-RAS (reflection absorption spectroscopy) and Raman analyses, it is expected that H 2 O stabilizes the more polymerized silicates anions rather than the depolymerized monomers. For the investigated slag compositions, slags under H 2 and NG/CG at 1550 °C had values of ψ = ( Q 0 + Q 1 )/( Q 2 + Q 3 ) (a measure of depolymerization) 75 and 55 less than slags under the CO/CO 2 …

Calibrating Carbon Measurements in Basaltic Glass Using ...

The effect of mixed volatiles (H2O + CO2) dissolved in basaltic glass on the calibrations of Fourier transform infra-red spectrometry (FTIR) and secondary ion mass spectrometry (SIMS) for H2O and CO2 is assessed. A series of mixed volatile-bearing calc-alkaline basalts were synthesized and analyzed using high-T vacuum manometry, FTIR, and SIMS.

FTIR imaging in diffusion studies: CO2 and H2O in a ...

High-resolution synchrotron-light FTIR imaging, in addition, also allows enhancement of CO2 diffusion along the hourglass boundary to be distinguished from diffusion along fractures in the grain. Therefore, FTIR imaging provides evidence that different diffusion mechanisms may locally combine, suggesting that the distribution of the target molecules needs to be carefully characterized in ...
