It is very important t h a t measurements o f the diffusion o f aromas and volatile substances in trace amounts (p.p.m.) through synthetic materials, such as PVC, PE and PP monolayers, be accurate and repeatable. The primary goal o f this w o r k was t o familiarize ourselves with t h e Aromatran@, a new, fully automated analytical instrument, for t h e measurement o f a ketone (2-butanone o r MEK) a t 23°C. A discussion o f results is provided, along with comments on the system's userfriendliness and t h e cost o f t h e tests.
