电子倍增器的使用说明
前言
GCMS在使用较长的一段时间后。检测器外加电压会逐渐升高，开始时通过清洗离子源，可以在自动调谐后使外加电压有明显地下降，随着使用时间的推移，逐渐清洗离子源的作用也不太明显了，这时一般就要申请工程师来清洗预杆和透镜，清洗后确实使外加电压有较大的下降，但是这样周期性地洗2-3次以后，清洗所带来的降压作用就不太明显了（清洗之前自动调谐电压为1.46KV，清洗后自动调谐电压1.42KV），这时工程师就建议通过更换电子倍增器来彻底改善电压状况，因此前日我们就更换了一次电子的倍增器，在换前，工程师给离子源、透镜、预杆做了清洗，然后装上新电子倍增器、预杆、离子源，抽真空后自动调谐，电压降到1.12KV，效果确实很明显。
作为GCMS的原装配件，在GCMS的说明书没有详细的介绍，所以从仪器说明书上没法知道它的具体细节，这次更换电子倍增，工程师带来了它的包装盒和说明书，等到工程师走之后，闲睱之时看了看这个使用说明书huigezi>我们的纪念，发现很有意思，所以抽空把它翻译出来，发上来大家共享，因为英文水平有限，有许多翻译不贴切的地方，欢迎批评指正，以期使大家能完全了学化妆
解它原本的涵意，促进更好地工作。谢谢！

（按照）以下本文所描述的基本程序，将使您的ETP电子倍增器获得最佳使用期限和最佳性能。
Storage of ETP Electron Multipliers
芹菜炒腐竹ETP电子倍增器的保存
The critical dynode surfaces of an ETP Electron Multipliers consist of a specially formulated and applied aluminum oxide material, which is very rugged and completely stable, even when repeatedly expod to room atmosphere. The original packing supplied by ETP is designed for long term storage. The multiplier is enclod in two aled plastic bags. The outer bag contains a silica gel package to minimize adsorption of moisture, which could otherwi lead to excessive outgassing upon installation.
ETP电子倍增器核心（关键性）的倍增器电极（打拿极）的表面是由特殊配方和专用应用的氧化铝材料组成。（这种材料）即使反复暴露在周围空气中依然非常坚固稳定。ETP提供的原始包装是为长期保存而设计。倍增器被封装在双层密封塑料袋中。外层袋子包含了干燥剂层使对湿气的吸附减到最小，否则可能导致在安装时（需要）过多地脱气。
Contained in its original packaging, the shelf-life of an ETP Electron Multipliers is guaranteed for up to two years from the date of shipment. If it is necessary to store the multiplier outside its original packaging, it should be kept in a clean, dust-free, low-humidity environment, such as a glass desiccator.
ETP电子倍增器原包装的有效保存期是在发运期两年内包修（包换），如果需要保存（去除原包装的）倍增器，要保存在象玻璃干燥器这样洁净、无尘、低湿的环境中。
Care and Handling of ETP Electron Multipliers
维护和操作电子倍增器
In order to minimize contamination, standard high-vacuum techniques are recommended
园艺
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 incread background noi 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 noi 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.
白发谁家翁媪的上一句
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.
利益观注意：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 – e 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 ud when installing or removing.
