气质联用仪—电子倍增器维护和操作
2011-05-07
In order to minimize contamination, standard high-vacuum techniques are recommended when handling ETP Electron Multipliers. Clean, powder-free gloves or finger cots should be worn to prevent the transfer of skin oils to critical or mounting surfaces of the multiplier. All tools, mountings, and equipment should be thoroughly cleaned prior to coming in contact with the multiplier.
为了减少污染，在ETP电子倍增器操作时推荐使用合乎标准的高真空技术。要戴上干净无尘的手套或手指套来防止皮肤油脂污染倍增器的核心或是安装表面。所有(用到)的工具，配件和设备在接触到倍增器之前都必须彻底清洗。
Care should also be taken to minimize exposure of the multiplier to dust or other airborne contamination.
维护(操作)时要注意尽量(采取)减少将倍增器暴露在灰尘和其它空气污染(的环境中的机会)。
Dust particles within the detector may result in increased background noise during operation.
在运行期间检测器内的粉尘粒子会导致(检测的)背景噪声增加
Exposure of the multiplier to high humidity should be avoided in order to minimize outgassing during initial operation. If the multiplier exhibits excessive noise due to adsorbed moisture, this condition may be rectified by either leaving the multiplier in high vacuum for about 24 hours, or by using a simple vacuum bake procedure.
为了使启动操作的脱气(时间)达到最小，应该尽量避免将倍增器暴露于高温度(的环境中)。如果由于吸附了湿气而使倍增器出现噪音过大(的现象)，需要将倍增器高真空(条件)下约24小时，或是用一个简单的真空烘烤过程。
NOTE: Most models may be backed in vacuum at up to 350℃. Some models may not be baked above 100℃. For information concerning temperature limitations, refer to the installation notes supplied with each ETP Electron Multipliers.
注意：大多数(零件)模块可以在真空下(烘烤)到350℃。一些(零件)模块不能烘烤超过100℃。关于温度限制的相关信息请参考每一个ETP电子倍增器的安装说明。
If baking must be done in atmosphere, the temperature must be limited to 120℃ (or lower than 100℃ for some models – see Note above). The multiplier should be heated and cooled slowly to avoid damage due to thermal shock.
如果烘烤要在正常大气压下，温度必须限制在120℃之内(或者一些零件模块要低于100℃-看上面的注意事项)。倍增器应该缓慢地加热和冷却以避免由于热冲击(温度激增)而损坏。
The rugged design of ETP Electron Multipliers reduces the risk of damage during handling, however, an electron multiplier is a precision component, and all reasonable care should be used when installing or removing.
ETP电子倍增器高低不平的(表面)设计减少了(手)操作期间受损的风险，无论如何，电子倍增器是个精密的部件，当安装和拆除时都应该尽可能地小心。
