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
