LC-MS study to reduce ion suppression and to identify N-lactoylguanosine 5'-monophosphate in bonito: a new umami molecule?
TLDR
The influence of ion suppression due to sample matrix effect was investigated and was found to substantially influence the total MS response of N-lactoyl GMP; by adjusting the LC conditions the response could be approximately 5-fold-enhanced. Expand
Phospholyl catalysts for olefin polymerization
Abstract Seventeen different phospholyl ligands were incorporated in a total of 22 zirconium complexes, (Phos) 2 ZrCl 2 , (Phos)(C 5 H 5 )ZrCl 2 , investigated in propylene polymerization catalysisExpand
Identification of N-glucosyl ethanolamine in wine by negative electrospray ionization with post-column chloride attachment and accurate mass determination on a triple-quadrupole mass spectrometer
Abstract In this study a specific taste modulating flavour-ingredient, N-glucosyl ethanolamine, was determined in two Beerenauslese wines using two different LC–MS techniques. For a first screeningExpand
Liquid chromatography with accurate mass measurement on a triple quadrupole mass-spectrometer for the identification and quantification of N-lactoyl ethanolamine in wine.
In this study a specific taste-modulating flavor ingredient, N-lactoyl ethanolamine, was determined in two Beerenauslese wines using preparative LC, as a first isolation and concentration step,Expand
Identification of N-gluconyl [corrected] ethanolamine in wine by negative electrospray ionization with post-column chloride attachment and accurate mass determination on a triple-quadrupole mass
TLDR
A specific taste modulating flavour-ingredient, N-gluconyl [corrected] ethanolamine, was determined in two Beerenauslese wines using two different LC-MS techniques using the application of the right MS(2) transitions for an unambiguous identification. Expand
Effects of procatalyst composition on the stereospecificity of a Ziegler-Natta catalyst system†
In propylene polymerization with MgCl2/TiCl4/phthalate ester catalysts, using 2,2,6,6-tetramethylpiperidine as external donor, it has been found that the fraction of atactic polymer formed increasedExpand
