336 Lithium Ion Attachment Mass Spectrometryfor the Direct Detection of OrganoarsenicCompounds in the Metallomics Studies
Direct detection of organoarsenic compounds is possible by ion attachment mass spectrometry(IAMS), due to the use of a direct sample insertion probe. With the advantage of this methodthat no separation approach is needed, direct detection of solid and liquid sample is possible,and only molecule peak is detected. It will be applicable for the direct analysis of variousorganometallic compounds in the latest metallomics studies.

344 Ordered Microdomain of DiprotonatedTetraphenylporphine Aggregate Formedat Dodecane/Aqueous H2SO4 InterfaceMeasured by Microspectrophotometry
In situ microscopic measurements showed that rhombic microdomains of diprotonated 5,10,15,20-tetraphenylporphine aggregates were formed at a dodecane/aqueous H2SO4 interface. Themicrodomains grew up gradually within 60 min. Their size and thickness were about 10–100µm and a monolayer level, respectively. The in situ absorption spectrum of a single
anisotropy of individual microdomainsrevealed that they had an orderedstructure where the H2tpp2+ aggregateshad no freedom of rotation, like singlecrystals. The present study demonstratedthat the liquid/liquid interface was areaction field of ordered microdomainsof a monolayer level thickness for thefirst time.
