September 29, 1983
Author(s)
Anzor I. Mikaia, Vladimir G. Zaikin, Valentin Vdovin
Decomposition of cyclopropane and cyclobutane containing compounds with Carbon, Silicon and Germanium atoms under mass spectrometry conditions is discussed.

Reaction chromato-mass spectrometry when studying cyclopropane compounds

May 1, 1983
Author(s)
Anzor I. Mikaia, Lyudmila Medvedkova, Vladimir G. Zaikin, Valentin Vdovin, A Kamisheva
A GC-MS method for structure elucidation of cyclopropane compounds is developed. The method includes the use of hydrogenolysis microreactor in the inlet system of a GC-MS and H2 or D2 as carrier and reagent gas.
