Positive chemical ionization triple-quadrupole mass spectrometry and ab initio computational studies of the multi-pathway fragmentation of phthalates

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).

Evaluation of two sample treatment methodologies for large-scale pesticide residue analysis in olive oil by fast liquid chromatography–electrospray mass spectrometry

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?

Electrospray mass spectrometric study of homogeneous catalytic system Pd(CF3COO)2-Ph2P(CH2)3PPh2-MeOH/Me2CO-H2O for copolymerization of ethylene and carbon monoxide

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.
