This study was done to see if different volatile chemicals are given off by diverse varieties of cotton, or by cotton grown in various locations. Such differences could be used to 'fingerprint' varieties and/or locations, helping researchers understand how the chemical composition of cotton fibers depends on variety or location of growth.
Technical Abstract: Our first studies of volatiles were undertaken to assess whether volatile compounds associated with raw fibers are in a quantity sufficient to pose a problem with moisture analyses that dry in an oven at 110 C. Samples of the same cotton variety grown in different locations showed different patterns. On the basis of that work, a more comprehensive study has been started to learn whether those differences are significant. We report here results of preliminary studies of volatiles from seven cotton fiber samples.
