ICP光谱仪是一种分离和检测不同同位素的仪器。即根据带电粒子在电磁场中能够偏转的原理，按物光原子、分子或分子碎片的光量差异进行分离和检测物光组成的一类仪器。已经在环境、生物、地光、冶金、工业、医学中广泛应用。

ICP spectrometer is an instrument for separating and detecting different isotopes. That is, according to the principle that the charged particles can be deflected in the electromagnetic field, a kind of instrument which is composed of the light and the difference of the light quantity of the atom, molecule or molecular fragment is detected and detected. Has been widely used in environmental, biological, light, metallurgy, medicine, industrial.

ICP光谱仪对实验室电源的要求，用户必须提供安全和干净的地线，最好不要与其他干扰大的仪器设备共用一个地线，地线的噪音会影响光谱仪正常工作，绝不能使用电源的中线作为安全地线，接地电阻要满足厂家要求。接地要求的目的，一是保障人身安全，二是保障仪器正常工作

ICP spectrometer on the laboratory power supply, the user must provide a safe and clean ground, best not to interfere with the other large equipment sharing a ground wire, the noise will affect the spectrometer normal work, do not use power line as safety wire, grounding resistance to meet the requirements of manufacturers. Grounding requirements, one is to protect personal safety, two is to protect the normal work of the instrument

几乎所有ICP光谱仪都要求专线供电，也就是从实验楼总配电室为光谱仪拉一根专用电源线，包括专门的地线，单独给光谱仪供电，一般大型光潜仪都采用此方式。这种方式既可避免其他设备对光谱仪的干扰，同时也避免光谱仪对其他仪器的干扰。

Almost all of the ICP spectrometer requires special power supply, which is from the floor of the total distribution room for pulling a dedicated power line spectrometer, including special wire, to separate spectrometer power supply, the general large-scale spectrometer are used in this way. This method can not only avoid the interference of other devices to the spectrometer, but also avoid the interference of the spectrometer to other instruments.
