Deconvolution, spectra

Fig.n.9 Deconvolved mass spectra [deconvolution by a maximum entropy algorithm (MaxEnt) supplied by instrument manufacturer] for S-peptide and S-protein, showing differences upon oxidation with 15 mM H2O2 using 15 mM Gin as scavenger. 

In the UVA IS spectrum of sample Vo.iMgo,90x CT bands of isolated tetrahedral V [12] can be identified by spectra deconvolution at 224, 268 and 326 nm (Figure 2a). They arise most likely from magnesium orthovanadate detected, besides MgO, as a minor com-... 

Figure 4. Left ICI-Epoxy acrylic latex transmission optical density spectra, measured experimentally, and compared to the fit obtained with its scattering and absorption components. Right Four absorption coefficients spectra deconvoluted from different compositions of ICI-epoxyacrylic lattices.

XPS measurements were carried out on an AXIS NOVA photoelectron spectrometer (Kratos Analytical, Manchester, UK). The surface atomic concentration was determined firom peak areas using sensitivity factors. Spectrum background was subtracted according to Shirley. The XPS peaks of the Ti species were analyzed by spectra deconvolution software (CasaXPS-Vision 2, Kratos Analytical, UK).
