“…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.
