The independent ejection slit used by 1. instruments is the first one in China, and the world is advanced. The characteristics of metal stitching are that the instrument is easy to debug and fast, and it is easy to exit the slit and increase the channel.

2.自动高压系统为世界先进水平。该系统可通过计算机控制每个通道提供8档高压，使同一通道可以在不同分析程序中得到应用，提高了通道的利用率和谱线最佳线性范围在分析不同材料中的采用，减少了通道的采用数量，降低了成本。

2. automatic high pressure system is the world's advanced level. The system can be controlled by computer in each channel is provided with 8 gear high pressure, so that the same channel can be used in different analysis procedures, improve the channel utilization and spectral line optimal linear range based on the analysis of the different materials, to reduce the number of the channels, reduce the cost.

3.自动描迹为世界领先水平，同类仪器国内空白。自动描迹可大大缩短校准仪器所用的时间，使仪器校准变得简单、方便，非专业人员既可进行描迹操作。仪器设有内部恒温系统。大大减小了环境温度变化对光学系统造成的漂移。

3. automatic tracing is the world leading level, and the same kind of instrument is blank at home. Automatic tracing can greatly shorten the time used to calibrate the instrument, so that the calibration of the instrument becomes simple and convenient, and the non professional personnel can carry out the tracing operation. The instrument has an internal thermostat system. The drift of the ambient temperature change to the optical system is greatly reduced.
