A study of the responses of electron absorbing derivatives in a high temperature electron absorption detector

The temperature dependency of the electron absorption process was investigated for a series of derivatives chosen to be representative of those employed for the analysis of biologically important compounds. Observations were made over the temperature range 200[degrees]C - 35O[degrees]C. The results are interpreted in accordance with Wentworth's kinetic model of electron attachment processes. In addition the analytical significance of high temperature operation is discussed. Operation to 35O[degrees]C was made possible by the successful development of a high temperature electron absorption detector which utilizes a [raised 63]Ni foil as the radioactive source. The design and operating parameters of this detector are presented.
