Abstract

Through the combined application of size-exclusion and reversed-phase liquid chromatography (off-line coupling), it is possible to analyze fragments of automobile direction indicator lenses (DILs) of differing origin for their content of low-molecular-weight substances or their subpolymeric components.

Because of their two-dimensional nature and the application of in-series detector combinations, the chromatograms have a high resolution and contain a host of analytically relevant data.

The material required is in the microgram range.
