    Description / Table of Contents: Zusammenfassung Ein mechanisiertes System zur Durchführung naßchemischer Aufschlüsse wird vorgestellt. Das System arbeitet kontinuierlich. Die Glasgefäße mit Proben und Aufschlußreagentien werden dem System auf einer Seite zugeführt, durchlaufen ein bestimmtes Temperaturprofil und werden an anderer Stelle wieder ausgegeben. Einwegglasampullen mit 10 bzw. 25 ml Inhalt dienen als Aufschlußgefäße. Die Veraschungszeit läßt sich im Bereich von 5 min bis zu 3 h einstellen. Die maximale Aufschlußtemperatur kann 300° C betragen.
    Notes: Abstract The system works in a continuous way. The glass vessels with the specimens to be tested and the decomposition agents are fed into the system on one side, run through a certain temperature profile, and are released again on the other end. Disposable glass vials with a content of 10 ml and 25 ml, respectively, are used. The incineration time can be set between 5 min and 3 h. The maximum incineration temperature can be 300°C.

    Notes: The 70 eV mass spectrum of phenyl ω-dimethoxyethyl telluride [C6H5—Te—CH2CH(OR)2, R=CH3]contains an intense peak at m/z 238 which corresponds to a rearrangement ion [C6H5—Te—OR]+. The formation of this species is further illustrated by the presence of a peak at m/z 241 in the spectrum of the hexadeuterated analog (R=CD3) and a peak at m/z 252 in the spectrum of the ethyl analog (R=CH2CH3). These combined results illustrate the presence of only one of the alkoxyl groups in the rearrangement ion. Several other abundant ions that contain oxygen but not tellurium are present in the spectra of these compounds. High resolution analyses have aided in the determination of the origin and composition of several of the characteristic ions formed upon electron impact fragmentation of phenyl ω-dimethoxyethyl telluride.
