| 主要附件及配置 |
1.对测试的固体样品粒径小于3 mm（包括一些薄膜衬底样品，长度一般≤1.5cm，宽度≤5 mm，因为顺磁样品管直径在3~5mm）。样品质量依据材料自身性质一般控制在几毫克至0.1克左右。另外，吸波材料不适合做EPR测试。2.对于液体样品，提供约0.5mL溶液；对需要检测自由基的捕获实验，测试样品需现场配制，一般捕获后的产物寿命仅分钟级的。此外，捕获剂本身对光、环境温度也都非常敏感，不易长时间暴露在空气环境中。3.对需要进行惰性气体保护的EPR原位、光照、低温等实验，需要课题组提供自制的样品管附件。1.There is no special requirement for solid powder samples to be tested, as long as the particle size of solid samples is less than 3 mm (including some thin film substrate samples, generally no more than 1.5cm in length and 5mm in width, because the paramagnetic sample tube diameter is 3~5mm). Sample quality is generally controlled from a few milligrams to about 0.1 grams according to the nature of the material itself. In addition, absorbing materials are not suitable for EPR testing. 2. For liquid samples, provide about 0.5mL solution; For free radical capture experiments, test samples need to be prepared in the field, because generally the life of captured products is only minutes level. In addition, the trapping agent itself is very sensitive to light and ambient temperature, and is not easy to be exposed to the air environment for a long time. 3. For EPR in-situ requiring inert gas protection, illumination and low temperature experiments, the research group shall provide self-made sample tube attachments. |
