标题
We report the first positive chemical ionization (PCI) fragmentation mechanisms of phthalates using triple-quadrupole mass spectrometry and ab initio computational studies using density functional theories (DFT). 出版机构:John Wiley & Sons, Ltd. 刊物名称:Journal of Mass Spectrometry 出版时间:2010 ISSN:1076-5174 数据源:报刊文摘
In this study, a comprehensive evaluation of two simple sample treatment methodologies has been carried out for the development of large-scale multi-residue methods for pesticide testing in olive oil. The proposed methodologies are based on (a) liquid? 出版机构:Elsevier Science 刊物名称:Journal of Chromatography A 出版时间:2010 ISSN:0021-9673 数据源:报刊文摘
n analytical method combining both a simple, fast and efficient solvent microextraction and a sensitive and selective monitoring mode, based on ion isolation ion-trap mass spectrometry (MS), was developed for analysis of perfluorinated compounds (PFCs) in biota. 出版机构:Elsevier Science 刊物名称:Journal of Chromatography A 出版时间:2010 ISSN:0021-9673 数据源:报刊文摘
Molecular mass ranges and average masses of fractions from a heavy Mexican crude oil (Maya) have been studied, using mainly size exclusion chromatography (SEC) and laser desorption-mass spectrometry (LD-MS). 出版机构:Elsevier Science 刊物名称:Journal of Chromatography A 出版时间:2010 ISSN:0021-9673 数据源:报刊文摘
AbstractThe catalytic system Pd(CF3COO)2-Ph2P(CH2)3PPh2-MeOH/Me2CO was studied by electrospray mass spectrometry. The {[Pd(dPPP)2]2+ [(dppp)2Pd(CF3COO)]+, [(dppp)Pd(CF3COO)]+, and [(dppp)Pd(CF3COO)2Pd(dppp)]2+} cations were found in the system. 出版机构:Springer US 刊物名称:Russian Chemical Bulletin 出版时间:1996 ISSN:1066-5285 数据源:报刊文摘
This review describes and discusses the advantages and limitations of proteomic approaches in the identification of biomarkers associated with chemotherapy resistance. 出版机构:Elsevier Science 刊物名称:Cancer Letters 出版时间:2010 ISSN:0304-3835 数据源:报刊文摘
This review summarizes the basic rules for the interpretation of atmospheric pressure ionization (API) mass spectra of small molecules written with the style primarily intended for beginners and low-experienced researchers with the mass spectra interpretation. 出版机构:Elsevier Science 刊物名称:Journal of Chromatography A 出版时间:2010 ISSN:0021-9673 数据源:报刊文摘
Planar separations, which include thin layer chromatography and gel electrophoresis, are in widespread use as important and powerful tools for conducting separations of complex mixtures. 出版机构:Elsevier Science 刊物名称:Journal of Chromatography A 出版时间:2010 ISSN:0021-9673 数据源:报刊文摘
These species are sampled during the combustion and quantified. For these measurements an automotive exhaust analyser, a gas chromatograph, coupled to a mass spectrometer and a flame ionisation detector are used, depending on the species to be measured. 出版机构:Elsevier Science 刊物名称:Energy Conversion and Management 出版时间:2010 ISSN:0196-8904 数据源:报刊文摘
AbstractThe presence of an acetyl blocking group at theN-terminus of the coat protein of papaya mosaic virus has been identified by FAB mass spectrometry. 出版机构:Kluwer Academic/Plenum Publishers 刊物名称:Journal of Protein Chemistry 出版时间:1989 ISSN:0277-8033 数据源:报刊文摘
