| Abstract: | The photocopy toners were collected and analyzed by fourier transform infrared spectroscopy (FT-IR). Photocopy toners produced by different factories and the different brands from same factories can be distinguished by this method. In this thesis an improved Munson's sampling method was employed. This method can avoid contamination of paper fiber. The results were stable and repeatable. |
