该部仪器包括电弧激发源、750毫米光学系统及鉴测系统等三部分。组装后装入外壳,放在一部有小轮子的手推车上。手推车抗震性能良好,操作和推动时不会损坏光谱仪。光谱仪随时可投入现场操作,不需要空调和预热。仪器操作简单。操作时,将一小巧手提式光枪对准待测材料,按下电钮激发电弧,所产生的光便通过一条石英光学纤维电缆进入光学系统。光被衍射光栅分成多条谱线,借助光电倍增管测量各条谱线的强度,所得之电信号被输入电子鉴测系统。如果样品与参比材料成分一致,光枪上绿灯亮;如
The instrument includes arc excitation source, 750 mm optical system and inspection system and other three parts. Assembled into the shell, placed on a small wheelbarrow. Anti-vibration carts good performance, operation and promotion will not damage the spectrometer. The spectrometer can be put into operation at any time without air conditioning and preheating. Instrument operation is simple. In operation, a small hand-held light gun is aimed at the material to be measured and the push button is used to excite the arc. The resulting light travels through a quartz fiber optic cable into the optical system. The light is split into a plurality of lines by a diffraction grating, and the intensities of the respective lines are measured by means of a photomultiplier tube. The resulting electric signal is input to an electron detection system. If the sample and reference material composition, light green light gun ;.
