B、the main characteristics
Low optical system with 750 mm focal length, palmer XingLong lattice structure, the dispersion effect is good, grating using grating Newport, companies in the United States and France JY company optimal products;
Chemical elements are of low metal industry needs analysis, including: trace carbon (C), phosphorus (P), sulfur (S). Applicable to the analysis of the corresponding matrix (base metal), such as Fe, Al, Cu, Ni, Co, Ti, Mg, zinc, Pb, Sn. Covers the whole scope of element analysis, can choose according to specific needs analysis element;
Low photomultiplier tube high pressure can be controlled by computer to each channel to provide several high pressure, the same channel can be applied in the different analysis program, greatly improve the utilization rate of the channel;
Independent exit slit structure, they sewed and optional wide, the position can be adjusted accurately, to improve the accuracy and precision of the element analysis;
Low spectral system adopts dynamic installation, can reduce the influence of temperature, material stress changes;
Low excitation light directly into the vacuum chamber;
With automatic constant temperature system, guarantee the light room temperature 35 ℃ + / - 0.2 ℃, can reduce the environmental temperature fluctuations on the instrument and the effect on the stability of the optical system;
The core of low spectrometer components all adopt the world famous professional manufacturers of products. The photoelectric conversion element using in Japan's hamamatsu photomultiplier tube; Other parts also bought more world famous manufacturers, instrument reliability were fully guarantee;
When using Japan's imports of photomultiplier tube: high signal-to-noise ratio, low dark current, long life;
Low light chamber vacuum automatic control technology, for the world advanced technology in the field of the spectrometer. Light vacuum application special MCU program of automatic control technology for automatic control, greatly improving the long-term stability of the instrument;
Low automatic high pressure system for the world's advanced level. The system can through the computer control for each channel 8 high pressure, so the same channel can be applied in the different analysis program, greatly improving the channel utilization and spectral lines of best linear range used in the analysis of different materials, reduced the number of channel of the, reduces the cost;
Low fully automatic computer control stepping motor automatic tracing for the world's advanced level, fully automatic tracing can greatly shorten the time required for calibration instruments, make calibration is simple, convenient, non-professional personnel as well as for tracing operation;
Each system is independent power supply, unitized design, the maintenance convenient and quick. Unitized design can achieve rapid maintenance of paraprofessionals, for Internet remote diagnosis instrument fault well prepared;
Analysis of low speed quick, the chemical composition of 20 seconds to closed all the channels. According to different analysis material, by analyzing the precombustion curve to determine the time, make the instrument with the analysis of the shortest possible time to achieve the optimal effect;
Chinese operating software under low xpista WINDOWS system, domestic users' convenience. Different levels of operator can call at any time in the help menu to guide to the operation of the instrument. And there are many languages system, can make it easy to use for foreign users.
