Using Py-GC and Py-FTIR techniques eight ...
(Py-GC/MS)provides a precise molecular composition and assists in the interpretation of the SERS spectra.In the present study,SERS was used in combination with XRF,normal Raman,FT1R,and Py-GC/MS to fully characterize two commercial samples of bistre and to determine specific biomarkers that ...
With the change of pyrolysis temperature, the chromatogram and mass spectra results take a large variety. The pyrolysates can help us to study the pyrolysis process of high performance fibers.doi:10.1007/s10973-010-1211-0Guang Ming CaiWei Dong Yu...

The FTIR spectra identified evolving gaseous products as CO2, CH4, HCNO, NH3, HCN, and NO. An AR material with a low H/C ratio promoted the formation of CO2 and HCN, but suppressed the yields of NH3 and CH4. The Py–GC/MS results suggested that abundant volatiles can be produced, ...
Some pigments and extenders could be efficiently identified by examination of the FTIR spectra and pyrolysis products. However, for most samples 渭-Raman spectroscopy investigation was required in addition to the mentioned techniques in order to achieve the complete chemical characterisation of organic ...
The silica template (SBA-15), carbon support (CMK-3) and catalyst (Ni@CMK-3) were characterized using XRD patterns, N2adsorption/desorption isotherms, Raman spectra, SEM images and ICP-MS analysis. XRD results showed that CMK-3 had uniform hexagonal arrays and metal loading on support did ...
