Determinação da relação siringila/guaiacila da lignina em madeiras de eucalipto por pirólise acoplada à cromatografia gasosa e espectrometria de massas (PI CG/EM) Determination of the siringyl/guaiacyl ratio in eucalyptus wood by pyrolysis-gas chroma-tography/mass spectrometry (PY-GC/MS)

Determinação da relação siringila/guaiacila da lignina em madeiras de eucalipto por pirólise acoplada à cromatografia gasosa e espectrometria de massas (PI CG/EM) Determination of the siringyl/guaiacyl ratio in eucalyptus wood by pyrolysis-gas chroma-tography/mass spectrometry (PY-GC/MS)

<abstract language="eng">The use of analytical pyrolysis combined with gas chromatography/mass spectrometry (Py-GC/MS) to determine the syringyl/guaiacyl ratio (S/G) in lignins from Eucalyptus spp woods was investigated. Sample of E. grandis and "E. urograndis" wood, with a...
