 Purge and trap GC/MS 



Limited studies microscale purge and trap were some of the last experiments 

 conducted for this dissertation. Although replicate analyses were conducted, the 

 results are somewhat preliminary. The results from these analyses are reported in 

 table 5-3. Complementary CI analysis was not conducted in these experiments. The 

 compounds listed in the table were derived from EI analyses only. Due to the 

 absence of information on compound r^ by CI, the identification process relied more 

 heavily upon EI library search purity values. The remark codes used in the table 

 reflect this. 



A remark code of (A) denotes a questionnable identity of a compound. If the 

 mass spectrum displayed a characteristic EI fragmentation pattern attributable to a 

 specific class, or if there was uncertainty in the structure due to isomers, a code of 

 (B) was used. If the compound was previously identified in the literature (reported 

 in table 5-1), the code (C) appears in the remark column. If the compound 

 identified is also reported as observed in cryo-focused analyses (table 5-2), a code 

 of (D) is present. Finally, a code of (E) in the table indicates that this compound 

 will be addressed further in the following text. 



The first designated component to be discussed is ethanol. This was only 

 identified to be present one time in the analyses of emanations from the author of 

 this dissertation. The particular analysis was conducted approximately 15 hours after 

 consumption of two glasses of wine for dinner the previous evening. This may have
