There are five (5) major volatile (c10)<br />
compounds when compared with a mixture of c6-c10 alkanes. Alkane<br />
mixtures are ideal for referencing unknown compounds using Kovat<br />
Indices. From this preliminary look we decided to perform a<br />
component analysis using the seven (7) major analtyes present.<br />
