“…Moreover, even if the apparatus is contaminated, it can easily be cleaned owing to the simple structure of TOFMS. Until now, LI-TOFMS has been applied to the online monitoring of several environmental samples, [19][20][21] and has also been applied to the analysis of compounds generated by heating and/or laser desorption from several types of samples, such as amino acids/ peptides, [22][23][24] polymers/oligomers, [25][26][27][28][29] and particles. [30][31][32] Recently, we applied this method to the measurement of pyrolysis products from samples of dried titanium dioxide (TiO2) nanoparticles coated by phenyltriethoxysilane (PTES), 33 which is one of the silane coupling agents.…”

Laser ionization time-of-flight mass spectrometry (LI-TOFMS) was applied to the direct measurement of a silane coupling agent in slurries. In the present study, a slurry with dispersed TiO2 nanoparticles treated with phenyltriethoxysilane (PTES) was prepared. As a result, the peaks for PTES could be observed from the slurry sample containing unreacted PTES, and no peaks were observed from the slurry sample where unreacted PTES was removed by washing. This method can be used to directly analyze surface coating agents, such as PTES in slurries, and would be useful for obtaining a direct understanding of the characteristics of slurries.

Abstract. The specific locations of the double bonds in linear olefins can facilitate olefin catalytic synthetic reactions to improve the quality of target olefin products. We developed a simple and efficient approach based on single photon ionization time-offlight mass spectrometry (SPI-TOFMS) combined with online ozonolysis to identify and quantify the linear olefin double bond positional isomers. The online ozonolysis cleaved the olefins at the double bond positions that led to formation of corresponding characteristic aldehydes. The aldehydes were then detected by SPI-TOFMS to achieve unique spectrometric Bfingerprints^for each linear olefin to successfully identify the isomeric ones. To accurately quantify the isomeric components in olefin mixtures, an algorithm was proposed to quantify three isomeric olefin mixtures based on characteristic ion intensities and their equivalent ionization coefficients. The relative concentration errors for the olefin components were lower than 2.5% while the total analysis time was less than 2 min. These results demonstrate that the online ozonolysis SPI-TOFMS has the potential for real-time monitoring of catalytic olefin synthetic reactions.
