⑵ Integrated design and high-precision processing in the vacuum chamber improves the duration of vacuum.

5. Vacuum Anti-Oil-Returning Technology

⑴Multi-level separating vacuum anti-oil-returning technology absorbs vacuum compaction and baffle valves to ensure the complete separation of vacuum optical chamber from vacuum pump during non-operation time.

⑵ The intermediate addition of vacuum oil filtering device ensures the oil inside the vacuum pump not to enter the vacuum chamber, and ensures CCD detectors and optical components to work under reliable situation.

6. Open-Access Inspire Stand

⑴Flexible sample clamp design of Open-Access Excitation Stand satisfies user on-site analysis of samples with different sizes and shapes

⑵ The small sample clamps in cooperative use can make the analytic precision of wire rods achieve 1.5 mm at the minimum.

7. Injection Electrode Technology

⑴The instrument adopts the most internationally-advanced injection electrode technology with tungsten used. Under the status of excitation, the electrode forms argon gas injection flow surrounded. Thus, there is no opportunity for the surrounding excitation points to contact external air so as to improve precision of excitation.

⑵ The attached specialized argon gas channel design significantly reduces the usage amount of argon gas and use cost for customers.

8. Integrated Gas Channel Block 

⑴ The excitation stand is made of alloys with good heat dissipation to achieve solidity, durability and cleaning convenience.

⑵ The gas supply system adopts integrated gas channel block and electrode self-flushing function to create good environment for excitation.

9. Full Digital Inspire Light Source

⑴ The system uses the most internationally-advanced plasma inspire light source, and generates ultra-stable energy release to excite samples in the environment filled with argon gas.

⑵ Full Digital Inspire Light Source ensures ultra-high resolution and high-stability output rate of plasma in the excitation samples.

⑶ Full Digital Inspire Light Source can satisfy inspire requirements for different type of materials.

10. High-Speed Data Acquisition 

⑴The instrument adopts high-performance CCD devices, UV coating technology and high-performance FPGA, DSP and ARM processors.

⑵The system has ultra-high functions of data acquisition and analysis, and can realize automatic real-time monitoring and control of the block operation status of optical chamber temperature, vacuum degree, argon gas pressure, light source and excitation chamber.

11. Ethernet Data Transfer

⑴ Ethernet cards and TCP / IP protocol are connected between computers and spectrometers to avoid electromagnetic interference, fiber aging defects. Meanwhile, the computers and printers are completely placed in external position for the benefit of promotion and substitution.

⑵ Complete network systems.

⑶ The system can remotely monitor the status of devices, operate the system through multiple channels, as well as control and monitor all the instrumental parameters.

12. Pre-Set Working Curves

⑴ The analysis programs in terms of elements and materials exist slight difference. The parameters of excitation and measurement have been adjusted before delivery. Customers can automatically choose optimal measurement conditions according to analysis programs.

⑵ Over a long period of time, the factory has been accumulating a large amount of experience and comprehensive international standard sample base. The factory pre-sets the working curves before delivery to benefit customers to put the device into use immediately after receiving.

⑶ The analysis range is attached to the technical specification (the system can plot or prolong working curves for free according to samples provided by customers).

13. Fast Analysis Speed

⑴ The fast analysis speed saves time for customers by finishing the element component analysis through all channels within 20 seconds.

⑵ According to the specific type of materials to be analyzed, it is available to make the instruments achieve the best analysis results within the minimum duration by setting pre-burning time and measurement time.

14. Multiple Matrices Analysis

⑴ The light-path design absorbs the structure of Rowland circle and vertically interleaved CCD arrays to ensure all the spectral lines to be received. No hardware is required to realize analysis of multiple matrices.

⑵ It is convenient to add up matrices, material types and analysis elements according to the requirements of production.

⑶ Compared with photomultiplier tubes (PMTs), spectrometers can significantly decrease use cost and increase the range of usage.

15. Software with Multiple National Languages

(1) The instrumental operating software is completely compatible with Windows system, and can be equipped with specific language versions according to user requirements.

(2) The software is easy to use. Even those staff without any knowledge and experience about spectrometers can easily use the software after a short simple training.
