A Knudsen cell monopol mass spectrometer for use in high temperature thermodynamics


A high temperature Knudsen cell was combined with a monopol mass spectrometer model MX 7304 with the ion source 1560014-T01 (Electron, Ukraine) despite the fact that these apparates have been designed for application in organic chemistry only. Relatively simple engineering details, as well as an extremely careful electrical optimisation of the operating conditions yielded a powerful measuring device for application in high temperature thermodynamics. Test measurements as well as the determination of the second law heats of sublimation of solid Fe, Co, Ni, Cu and Cr proved the efficiency of the new device.
