Main Features
|
1. High-performance optical system |
|
|
1. The arc flame generated by the excitation of the optical system is directly introduced into the vacuum optical chamber through the lens to realize the direct connection of the optical path and effectively reduce the loss of the optical path;
2. The design of high-performance optical system and the use of high-precision optical components can accurately determine the content of C, P, S, N and various elements in non-metallic elements;
3. The measurement results are accurate, with excellent reproducibility and long-term stability. |
|
|
2. Fast analysis speed |
|
|
1. The analysis speed is fast, saving valuable time for customers, and the elemental composition of all channels can be measured in about 20 seconds.
2. For different analysis materials, by setting the pre-burning time and measurement time, the instrument can achieve the optimal analysis effect in the shortest time. |
|
|
3. Anti-error system |
|
|
1. The new integrated technology breaks through the traditional valve design and eliminates the pollution of the light chamber. |
|
|
4. Vacuum anti-return oil technology |
|
|
1. Multi-stage isolation vacuum anti-return oil technology, using vacuum pressing and baffle valve to ensure that the vacuum light chamber is completely isolated from the vacuum when the vacuum pump is not working.
2. A vacuum oil filter device is added in the middle to ensure that the oil in the vacuum pump does not enter the vacuum chamber, and to ensure that the CCD detector and optical components work in a reliable environment. |
|
|
5. Vacuum chamber integration |
|
|
1. The unique optical chamber structure design makes the volume of the vacuum chamber smaller, and the vacuuming speed is less than half of that of the ordinary spectrometer.
2. The integrated design of the vacuum chamber and high-precision processing make the vacuum last longer. |
|
|
6. Multi-matrix analysis |
|
|
1. The optical path design adopts the Luolan garden structure, and the CCDs are arranged alternately up and down to ensure that all spectral lines are received, and multi-matrix analysis can be realized without adding hardware facilities. 2. It is convenient to increase the matrix and material types and analytical elements according to the needs of production. 3. Compared with photomultiplier (PMT) spectrometer, it can greatly reduce the cost and scope of use. |
|
|
7. Jet Electrode Technology |
|
|
1. Adopt the most advanced jet electrode technology in the world and use tungsten material electrode. In the excited state, an argon jet flow will be formed around the electrode, so that the surrounding area of the excitation point will not be in contact with the outside air during the excitation process, which improves the exciation accuracy.
2. Equipped with a unique argon gas circuit design, it greatly reduces the amount of argon gas used, and also reduces the customer's use cost. |
|
|
8. Fully digital excitation light source |
|
|
1. Fully digital excitation light source, using the most advanced plasma excitation light source in the world, the ultra-stable energy is released to excite the sample in an argon atmosphere.
2. Full digital excitation pulse, to ensure ultra-high resoluti
