電感耦合等離子體光譜儀是建立在調制原理上的儀器,經典光譜儀器都是狹縫光譜儀器,對工作條件有一定的要求,下面作下簡單的介紹。
Inductively coupled plasma spectrometer is based on the modulation of the principle of the instrument, the classical spectrum instruments are slit spectrometer, the working conditions have certain requirements, the following is a brief introduction.
電感耦合等離子體光譜儀工作的基本條件:
The basic conditions of inductively coupled plasma spectrometer:
1.rf系統能夠輸出持續、穩定、合適的能量到工作線圈。
The 1.rf system is capable of outputting continuous, stable and suitable energy to the work coil.
2.炬管安裝良好且通有純凈、流量適宜的氬氣。
2 the torch tube installation is good and pure, with suitable argon flow.
3.點火裝置向氣體中釋放適當的電荷。
3 the ignition device releases the appropriate charge to the gas.
4.如果其中某個條件沒有滿足則儀器不能正常點火。
4 if one of these conditions is not met the instrument cannot be fired.
另外,電感耦合等離子體光譜儀的功率放大部分的核心部件為功率它是一個大功率的真空電子管,內部有一細長的燈絲,當燈絲通電而RF系統未工作時,電流就會讓燈絲發熱并發射熱電子。
In addition, the power of inductively coupled plasma spectrometer amplification of the core parts of power as it is a high power vacuum tube, inside a slender filament lamp, when electric power is applied and the RF system does not work, will let the current heat and hot electron emission filament.
