Programmed probe thermal analysis and its use in the study of thermal decomposition of some trans-substituted derivatives of zeise's salt

A mass spectrometer equipped with a programmed probe and a total ion monitor may be used to study thermal decompositions by gradually heating the sample in the probe. The ion current is monitored and mass spectra taken at appropriate points permit the identification of decomposition products. Single ion monitoring can also be employed. The method has been used to examine a series of compounds formed by the replacement of the trans-Cl ligand of Zeise's salt. Pathways for the thermal decomposition are postulated.
