Chemiluminescence (CL) is the term used to describe the emission of light as a direct result of a chemical reaction. CL originating from oxidative degradation processes in polymers was reported in the early 1960s. Technological developments have resulted in CL becoming a sensitive and well-established technique that is used for prescreening tests.
Features and Benefits
- CL is very selective – CL occurs only as a result of the oxidative decomposition reaction of the sample
- CL is extremely sensitive – measurements performed at lower temperatures are of greater practical relevance
- High-pressure CL – high pressures dramatically accelerate oxidative degradation and suppress vaporization
- Unique imaging possibilities – allow the initiation and propagation of oxidative degradation to be studied
- Simultaneous CL and DSC measurements – DSC provides complementary information on thermal effects such as glass transitions and melting
- Modularity – an HP DSC 1 or an HP DSC827e can easily be upgraded to include CL capability
