High-performance optical system

The arc flame generated during excitation of the optical system is directly introduced into vacuum optics by the lens room, realize direct optical path through, effectively reduce optical path loss; The measurement results are accurate, with excellent repeatability and long-term stability.

High-speed data acquisition

The instrument  uses high-performance CMOS detection components, with the individual ultra-high-speed data acquisition and analysis function of each CMOS, and can  monitoring and control the operating status of modules automatically and real-time, such as the light chamber temperature, vacuum degree, argon pressure, light source, excitation chamber, etc.

Jet electrode technology

Using advanced jet electrode technology internationally, using tungsten electrode material electrodes, an argon jet stream will form around the electrodes in the excitation state, so that during the excitation process, the excitation point will not come into contact with external air, improve the excitation accuracy, and the unique argon gas circuit design greatly reduces the use of argon and reduces the cost of customers.

Plug-out lens

The vacuum optical system adopts a unique incident window and is isolated from the vacuum system, and can be operated in the working state of the vacuum system. The optical lens adopts a plug-in lens structure, making daily cleaning and maintenance convenient and fast.

Digital excitation light source

Digital excitation light source, using the most advanced plasma excitation light source in the world, super stable energy is released in the argon environment to excite samples;

Fully digital excitation pulses ensure ultra-high resolution and high stability output of plasma excitation;

The various parameters of the light source can be adjusted arbitrarily to meet the excitation requirements of various different materials.

Vacuum oil prevention technology

Multi-stage isolation vacuum oil-return technology uses vacuum differential pressure valve to ensure that a vacuum oil filter device is added between the vacuum optical chamber and the vacuum when the vacuum pump is not working, ensuring that the oil in the vacuum pump does not enter the vacuum chamber and ensure that the CMOS detector and optical components work in a reliable environment.

Ethernet data transmission

The computer and the spectrometer use Ethernet card and TCP/IP protocol to avoid electromagnetic interference and the disadvantages of fiber aging. At the same time, the computer and printer are  external completely, making it easier to upgrade and replace. The instrument status can be monitored remotely, and the multi-channel control system can control and monitor all instrument parameters.

Prefabricated working curve

There is a standard sample library of different materials and grades. The factory prefabricated working curve when the instrument leaves the factory, which is convenient for installation and debugging and timely put into production; there are slight differences according to the analysis procedures corresponding to the elements and materials, the excitation and testing parameters have been adjusted when the instrument leaves the factory, and the optimal testing conditions can be automatically selected according to the analysis procedures.
