Analysis of Molecular Species of Organic Compounds Dispersed in Polymer Layer Using LDMS and SIMS

Many important contributions have been recently made, to our knowledge, to the analysis of organic compounds using LDMS or SIMS. Most of these works have been carried out on specific samples such as thin layer compounds deposited on a metal surface [1]. Recently, characteristic secondary ions (SI) of various kinds of practical polymer films were shown by Briggs [2, 3]. In his paper, the importance of surface potential stabilization attained by selecting the optimum parameters for primary ions and electron flood was emphasized to obtain finger print SI mass spectra of individual polymers.
