关于色谱方面增大S/N信噪比?小女子做仪器方便的,自己搭建了一台 毛细管电泳仪 ,投了一篇电泳杂志,编辑回信中提到:This suggests that the S/N could be improved by amplifying the PMT signal and/or changing the A-D conditions (smaller range, more bits for A-D conversion)。说信噪比可以通过放大PMT信号和改变A-D 转换器 的条件来提高。小妹知识面不广,还请求哪位懂这方面的大虾详细的指点下,确实说得太笼统了,理解不了编辑的深层意思、谢谢侬!查看更多4个回答 . 5人已关注
又一句费解的, "4 off"是什么意思? The spray ring shall be supplied with 4 off spray nozzles with the following duty: Flow per nozzle: ... Max. pressure drop: ... Nozzle type: 120 degree full cone Density: ... Viscosity: ... 请问上文中的4 off和full cone是什么意思? 我在询价书的零备件列表里还看到过 Earthing Brackets (2-off), 看来跟4-off意思差不多。查看更多10个回答 . 3人已关注
