^aSamples were analyzed, following appropriate derivatization, by full-scan GC-MS on both BPX-5 and HP-1 capillary columns. 

^bComparison was with unlabeled standards (std.), and all samples were coinjected with parafilm so that KRI values could be compared. 

^cData are from full scan on an HP-1 column.
