主要技术特点 2. Main technical characteristics
High-performance optical system
The arc flame generated when the optical system is excited is directly introduced into the vacuum optical chamber by the lens, so that the optical path is directly passed and the optical path loss is effectively reduced;
The CMOS element used can accurately determine the content of non-metal elements such as C, P, S, As, B, N and various metal elements;
Accurate measurement results, excellent repeatability and long-term stability.
Automatic optical path calibration
Automatic optical path calibration, the optical system automatically scans the spectral lines to ensure the correctness of the reception, and eliminates tedious peak scanning work;
The instrument automatically recognizes the specific spectral line and compares it with the original storage line, determines the drift position, finds out the current pixel position of the analysis line for measurement.
Plug-in lens design
The vacuum optical system uses a unique entrance window and vacuum isolation, which can be operated in the working state of the vacuum system. The optical lens uses a plug-in lens structure, which is convenient and fast for daily cleaning and maintenance.
Vacuum chamber integration
The unique light chamber structure design makes the vacuum chamber volume smaller, and the evacuation time is only 1/2 of the ordinary spectrometer;
The integrated design of the vacuum chamber and high-precision processing make the vacuum more durable.
Vacuum anti-return oil technology
Multi-stage isolated vacuum anti-return oil technology, using vacuum differential pressure valve to ensure that the vacuum light chamber is completely isolated from the vacuum when the vacuum pump is not working
A vacuum oil filtering 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 CMOS detector and optical components work in a reliable environment.
The flexible sample holder design of the open-type excitation machine meets the sample analysis of various shapes and sizes at the customer site;
With the use of a small sample holder, the minimum wire analysis can reach 3mm.
Jet electrode technology
Using spray electrode technology, using tungsten material electrode, in the excitation state, an argon gas jet will be formed around the electrode, so that the excitation point will not be in contact with the outside air around the excitation process, which improves the accuracy
Equipped with a unique argon gas path design, greatly reducing the amount of argon gas used and also reducing the cost of use for customers.
Integrated pneumatic module
The pneumatic system adopts a pneumatic module maintenance-free design, replacing the solenoid valve and flow meter, and the electrode self-purge function, creating a good environment for excitation.
Digital excitation light source
Digital excitation light source, using advanced plasma excitation light source, super stable energy release to excite the sample in argon environment;
Full digital excitation pulse to ensure ultra-high resolution and high stability rate output of the excited sample plasma;
The parameters of the light source can be arbitrarily adjusted to meet the excitation requirements of various materials.
High-speed data acquisition
The instrument uses high-performance CMOS detection elements, each CMOS has a separate ultra-high-speed data acquisition and analysis function, and can automatically monitor and control the operating status of modules such as light chamber temperature, vacuum, argon pressure, light source, and excitation chamber.
Ethernet data transmission
The Ethernet card and TCP / IP protocol are used between the computer and the spectrometer to avoid electromagnetic interference and the disadvantages of fiber aging. At the same time, the computer and printer are completely external, which is convenient for upgrading and replacement;
The instrument status can be monitored remotely, and the multi-channel control system controls and monitors all instrument parameters.
Prefabricated working curve
There are standard sample libraries of different materials and brands, and the factory pre-made working curve when the instrument leaves the factory, which is convenient for installation and debugging and put into production in time;
There is a slight difference according to the analysis program corresponding to the element and material. The excitation and test parameters have been adjusted at the factory. The test conditions can be automatically selected according to the analysis program.
The technical scope is attached with the analysis range (and the working curve can be drawn or extended for free according to the standard samples provided by the user).
Fast analysis speed, only one analysis can be completed in 20 seconds;
For different analysis materials, by setting the pre-burn time and measurement time, the instrument can achieve excellent analysis results in a short time.
The optical path design adopts the Roland circular structure, and the detectors are arranged alternately up and down to ensure that all the spectral lines are received. Multi-matrix analysis can be achieved without adding hardware facilities;
It is easy to add substrates and material types and analysis elements according to production needs (no hardware cost).
Software Chinese and English system
Instrument operating software is fully compatible with Windows 7/8/10 system;
The software is easy to operate, even those who do n’t have any knowledge and experience in spectrometer can get started with simple knowledge training.
