Abstract:
Microencapsulated spheroids containing a coded, volatile electron absorbing substance are dispersed into a material to be regulated such as crude oil in a tanker. Samples of the material such as an oil spill are collected and the source of the material is determined by electron capture gas chromatographic detection of the electron absorbing substance.
