 possible, as well as the order within each group, for additional tables in this chapter 

 which report qualitative identification of components. 



A total of at least 23 methods, including GC/MS, were used in the literature 

 sources to identify compounds listed in this table. The low r^ compounds listed in 

 this table may be difficult to confirm by the GC/MS methods employed here. There 

 are compounds in this table for which the volatility is extremely high; these 

 compounds are not expected to be effectively collected on glass beads, nor are they 

 likely to remain on the glass beads until desorption in the GC. Compounds which 

 fall under this category are noted by an (A) in the remarks column of the table. 



The majority of compounds listed were determined using separation methods 

 other than GC. Some compounds in the table were separated by, for example, liquid 

 chromatography (LC). These compounds are involatile and well chromatographed 

 by LC but may not be amenable to GC. Compounds which fall under this category, 

 such as involatiles, salts, or compounds which thermally decompose in the 

 temperature range of analyses, are not amenable to GC analysis; therefore they are 

 noted by the remark code (B) in the Table 5-1. 



There is an implicit comment made in one of the literature sources that the 

 presence of the complete series of saturated carboxylic acids from acetic acid up to 

 octadecanoic acid is observed in human perspiration, without specifically providing 

 the data to confirm this [30]. Therefore, completion of the series is noted by the 

 presence of (C) in the remarks indicating the compound(s) of lower carbon number
