Pyrolysis-gas chromatography-isotope ratio mass spectrometry of polyethylene.
Polyethylene is probably the most used plastic material in daily life and its accurate analysis is of importance. In this communication the chemical structure of polyethylenes is studied in detail using conventional analytical pyrolysis (Py-GC/MS), bulk stable isotopic analysis (IRMS) and pyrolysis compound specific stable isotopic analysis (Py-CSIA) to measure stable isotope proportions (δ(13)...
متن کاملPaints and Coatings: Pyrolysis: Gas Chromatography
In this review, the principles behind, and the utility of, fractionation of subcellular organelles by centrifugal techniques have been explored. Common methods used, and a review of the advantages and disadvantages of certain experimental tools (centrifuges, rotors, and aqueous media used for fractionation) were also reviewed and tables and graphs useful for designing protocols were also provided.
متن کاملHydrocarbon phenotyping of algal species using pyrolysis-gas chromatography mass spectrometry
BACKGROUND Biofuels derived from algae biomass and algae lipids might reduce dependence on fossil fuels. Existing analytical techniques need to facilitate rapid characterization of algal species by phenotyping hydrocarbon-related constituents. RESULTS In this study, we compared the hydrocarbon rich algae Botryococcus braunii against the photoautotrophic model algae Chlamydomonas reinhardtii u...

(tetrahydrofuran) at 703C for 16 h. The ester residue is then converted to a 6,6-dideuteriohexose residue, the O-methyl ethers of which are easily distinguishable by GC-MS of the derived alditol acetates. An alternative to acid hydrolysis that is applicable to most polysaccharides and glycoconjugates, including those containing acid-labile residues or glycosidic linkages resistant to hydrolysis...
متن کاملCharacterization and Evaluation of Light Hydrocarbon in Northwestern Iranian Crude Oil by Detailed Hydrocarbon Analysis (D.H.A)Gas Chromatography
Lighthydrocarbons are commonly used to evaluatecrude oils to determine oil families in reservoirs undergone some kind of alteration process. In this study crude oil contentsfromNorthwestern IranDelta (samples A, B and C)were analyzed in order to evaluate the IranDelta petroleum system independent of higher molecular weight markers. Ultra high resolution gas chromatography was used in separation...
