ABSTRACT:
The present invention is directed to a novel apparatus for measuring the transmission or permeation of gases, flavors, aromas and volatile substances through films and membranes. The instrument of the present invention also provides the capability of high rate testing in order to allow the expedient analysis of multiple film samples within a reasonable amount of time. This invention also provides an instrument and method for extremely high sampling rate of permeant gas with little or no background noise, whereby detection sensitivity is greatly enhanced relative to conventional testing instruments.
