X‐ray fluorescence of the chlorine atom is a suitable method for identifying vinyl in a mixed plastics stream in municipal solid waste. The chlorine X‐ray is weak and does not penetrate paper labels. There is also a rapid decrease in measured chlorine X‐ray intensity as the sample is moved away from the X‐ray source and detector which could be a potential problem for bottles of uneven shape.
