1. Plasma excitation and impedance matching use automatic technology； low reflected power,；standing-wave ratio (SWR) is less than 1.25.
2. Axial viewing position, longer torch is used to reduce the fluctuation of the tail flame, the cold cone is placed at the tail flame to prevent the tail flame from entering the viewing hole.
3. Argon Flows: MFC on nebulizer gas, plasma gas, auxiliary gas. All gas flows under computer control.
4. Small volume, light weight, long life, low noise, high coupling efficiency, stability of power output <0.1%, greatly improve the accuracy of analysis;
5. One wavelength scan is performed before sample measurement, which can avoid wavelength shift after long-term measurement to affect measurement accuracy.
6. Upgraded spectrum database, data information up to 50,000.
7. Interference spectral line automatic filter function
8. Automatic serial communication
9. Scanning mode: Turbo vortex rod, driven by computer-controlled stepper motor, minimum scan step is 0.0006nm.
