2. Main technical features
High performance optical system
When the optical system is excited, the arc flame is directly led into the vacuum optical chamber by the lens to realize the direct optical path and effectively reduce the optical path loss;
The content of nonmetallic elements and various metal elements can be accurately determined by using high-precision CMOS components;
The results were accurate and stable.
Automatic light path calibration
Automatic optical path calibration, automatic spectral line scanning of optical system to ensure the correctness of receiving and avoid cumbersome peak scanning work;
The instrument automatically identifies the specific spectral line and compares it with the original storage line to determine the drift position, and finds out the current pixel position of the analysis line for determination.
Design of plug in lens
The vacuum optical system adopts a unique incident window and vacuum isolation, which can be operated in the working state of the vacuum system. The optical lens adopts the plug-in lens structure, which is convenient for daily cleaning and maintenance.
Vacuum chamber integration
The unique light chamber structure design makes the volume of vacuum chamber smaller, and the vacuum time is only 1 / 2 of that of ordinary spectrometer;
The integrated design of vacuum chamber and high precision processing make the vacuum more durable.
Vacuum oil return prevention technology
The vacuum pressure differential valve is adopted to ensure that the vacuum chamber is completely isolated from the vacuum when the vacuum pump is not working
A vacuum oil filter is added in the middle to ensure that the oil in the vacuum pump does not enter the vacuum chamber, and the CMOS detector and optical components work in a reliable environment.
Open platform
The flexible sample holder design of the open excitation machine can meet the requirements of sample analysis of various shapes and sizes on the customer site;
With the use of small sample clamp, the minimum analysis of wire rod can reach 3 mm.
Jet electrode technology
With the international advanced jet electrode technology and tungsten electrode, the argon jet flow will be formed around the electrode in the excitation state, so that the excitation point will not contact with the external air during the excitation process, thus improving the excitation accuracy
With the unique design of argon gas circuit, the use of argon is greatly reduced, and the use cost of customers is also reduced.
Integrated gas circuit module
The gas circuit system adopts the gas circuit module maintenance free design, replacing the solenoid valve and flowmeter, and electrode self purging function, which creates a good environment for excitation.
Digital excitation light source
The digital excitation light source adopts the most advanced plasma excitation light source in the world, and the ultra stable energy is released to excite the sample in argon environment;
The full digital excitation pulse ensures the ultra-high resolution and high stability output of the excited sample plasma;
The parameters of the light source can be adjusted arbitrarily to meet the excitation requirements of different materials.
High speed data acquisition
The instrument adopts high-performance CMOS detection elements, and has the function of ultra-high speed data acquisition and analysis for each CMOS chip, and can automatically and real-time monitor and control the operating state of modules such as the temperature of the light chamber, vacuum degree, argon pressure, light source, excitation chamber, etc.
Ethernet data transmission
The Ethernet card and TCP / IP protocol are used between the computer and the spectrometer to avoid electromagnetic interference and fiber aging. At the same time, the computer and printer are completely external, which is convenient to upgrade and replace;
The instrument status can be monitored remotely, and all instrument parameters can be controlled and monitored by multi-channel control system.
Precast working curve
It is equipped with standard sample library of different materials and brands, and the working curve is prefabricated in the factory when the instrument leaves the factory, which is convenient for installation and commissioning and timely put into production;
According to the analysis program of elements and materials, the excitation and test parameters have been adjusted before delivery, and the optimal test conditions can be automatically selected according to the analysis program;
The analysis range is attached in the technical specification (and the working curve can be drawn or extended free of charge according to the standard sample provided by the user).
Fast analysis speed
The analysis speed is fast, only 20 seconds is needed to complete the analysis;
According to different analytical materials, through setting the pre ignition time and measurement time, the instrument can achieve the best analysis effect in the shortest time.
Multi matrix analysis
The detector is arranged alternately from top to bottom to ensure that all spectral lines can be received without additional hardware facilities;
It is convenient to increase the types of matrix and materials and analysis elements (no hardness) according to the needs of production
