請問做TG/DTG時,升溫速率對失重峰有何影響? 增大加熱速率失重峰是前移還是后退,還是不變呢??? 謝謝指教! |

| There are a lot of factors influenced the results of TG-DTG analysis such as the gas protected atomshpere, the rising speed, the catalysts itself and so on. Normaaly, if the sppeed is too fast, it may cause sintering or aggragation on the surface. The samples cannot decompose fully. If the speed is too slowly, the adsorbed peaks may shift. Normarlly, you can operate at 8 degree/min under argon enviroment. This is the unversial strategy. |

| Sorry to forget to add some information. Y ou can find some handbooks about your instrument. From that handbook, you can find the influenced factors. Another choice, you can review some books. In my institute, I listened one speech of TG-DTG analysis. But I forget where I have stored. Because I donot use TG-DTG analysis here. During my Master study, I use often. |
