The enrichment factors determined by Rayleigh equations were −29.2 ± 2.6‰ for δ13C (εC) and −227.6 ± 13.5‰ for δ2H (εH), respectively.
WebLinear byproducts of the synthesized polymer were removed by means of inverse spin fractionation, using the solvent cyclohexane (CH) and the precipitant acetone (AC). A well-defined fraction (M w = 17.5 kg/mol, M w /M n = 1.8) of the branched polyisoprene obtained in this manner was used to determine different phase diagrams with branched and/or … WebThe magnesium and silicon isotopic correlation lines shown in Figures 5 and 8, respectively, are consistent with fractionation via Rayleigh distillation (see discussion in Davis et al., 2015) suggesting, to first order, that a single fractionation factor characterizes evaporation (for each element) from a continuously well-mixed melt.
WebAn interesting application was presented by Breuckmann et al. who determined C, H, N and O in plastics using the WDXRF Rayleigh and Compton scattering spectra from a rhodium source and partial least squares regression. 119 The method was applied to 84 polymer samples, some of which were thermoplastics and others thermoset plastics (e.g. …
