The QL-5800A spark direct reading spectrum analyzer produced by Nanjing Kirin Optoelectronic Spark Direct Reading Spectrometer is a fast quantitative analysis instrument for analyzing the composition of ferrous metals and non-ferrous metals. This instrument is widely used in metallurgy, machinery and other industrial sectors. It performs online analysis before smelting furnaces and laboratory product inspections. It is one of the effective means to control product quality.
1. 750mm focal length grating design, Par-Long device, high vacuum, high resolution, high sensitivity and other characteristics; Since the machine-engraved grating can generate a relatively light spectrum, the line selection is more flexible, thereby avoiding spectral interference.
2. The instrument structure is designed reasonably, the electronic system adopts international standard cages, highly integrated circuit design, and low failure rate.
3. Fast analysis speed, good repeatability and good stability.
4, using a highly stable digital light source, the excitation frequency changes between 100-1000Hz, analysis of different samples, you can choose different excitation parameters, can achieve analysis results.
5. Adopt highly integrated acquisition and control system with high degree of automation.
6. The photomultiplier tube is adopted, which has the characteristics of small dark current, high signal-to-noise ratio and long service life. .
7. Analyze the scanning process to scan all elements at the same time, the scanning process is simple, and the deviation of each element relative to the matrix element can be quickly analyzed.
8. During the process of exciting the samples, there is no need to cool the excitation table with water, and continuous analysis of the samples can also achieve better data.
9. The measurement and control system adopts single board computer for measurement and control, and performs data exchange with the host computer to improve the operating speed.
10. The negative voltage of the photomultiplier tube of each channel is adjusted by computer software. The negative voltage of the channel is adjusted in 8 steps, which greatly improves the utilization of the channel and the linear range of the analysis line in the analysis of different materials. The number of adoptions has reduced costs.
11, can be used for a variety of matrix analysis: Fe, Co, Cu, Ni, Al, Pb, Mg, Zn, Sn and so on.
12. The operating software under pure Chinese Windows system is simple and easy to understand.
13. The computer software has a database system, which facilitates the query and printing of measurement data. It can also remotely transmit data through the network, which is convenient and fast.
14. Each system is independently powered and composed of units, which is easy to use and simple to maintain.
15. The use of constant temperature measures in the optical part ensures the normal operation of the instrument, thereby reducing the environmental requirements.
16. The high-precision linear motor is used to scan the seams, and the speed is fast.
17, using the overall exit slit to increase the channel.
