| Abstract: | Photocopy toners were collected and analyzed with Pyrolysis Gas Chromatography Spectrometry (Py-GC). Minor differences in composition of photocopy toners of different factories and different brands of the same factories were detected. In the study, an improved Munson's sampling method was employed and effects of paper fiber were eliminated. Results of the method were stable and repeatable, and the discriminating rate readied 90.3%. |
| Keywords: | Py-GC photocopy toner qualitative analysis |
