ABSTRACT:
A test strip, methods for making and using the test strip, and a kit are described, which allow for the simple and efficient determination of the acetaldehyde content in a polyester polymer. The strip and methods have application, for example, in the manufacture of polyethylene terephthalate preforms and containers, where existing methods for testing for acetaldehyde are cumbersome and time consuming.
