The use of instrumentation is an integral part for the analysis of compounds.   Gas Chromatography/Mass Spectrometry (GC/MS), in particular, identifies different types of compounds present in a mixture through separation and subsequent identification based on specific chemical properties. Advances in GC/MS instrumentation allow for a larger range of chemicals to be analyzed due to its improved design and increased sensitivity. These enhanced parameters allows for the investigations of more volatile samples.  The direct insertion probe (DIP), a feature on some GC/MS instruments, permits the analysis of low volatile organic species by directly inserting them into the MS ionization chamber.  The objective of this research was to determine appropriate methods for the analysis of organic materials using traditional GC/MS and DIP techniques. Such methods focus on the analysis of known materials and applying them to new materials not yet fully characterized. Specifically, these new materials of interest include benzodithiophenes - an important class of organic materials used in a variety of electronic devices. The preliminary results of our method development suggested that unoxidized benzodithiophenes can be analyzed by GC/MS while oxidized molecules required DIP analysis.<br/>
