main features
1, 750mm/1000mm focal length grating design, Pa-Longge device, high
vacuum, high resolution, high sensitivity, etc.; because the
machined grating can produce higher-order spectra, the line
selection is more flexible, thus avoiding spectral interference.
2, the instrument structure design is reasonable, the electronic
system uses international standard cage, high integrated circuit
design, low failure rate.
3. The analysis speed is fast, the repeatability is good, and the
stability is good.
4. Using a highly stable digital light source, the excitation
frequency varies between 100-1000 Hz, different samples can be
analyzed, and different excitation parameters can be selected to
achieve the best analysis results.
5. Highly integrated acquisition and control system with high
degree of automation.
6, the use of imported photomultiplier tube, with dark current,
high signal to noise ratio, long service life and so on. .
7. The analysis scan process can scan all the elements at the same
time. The scanning process is simple, and the deviation of each
element relative to the base element can be quickly analyzed.
8. During the process of exciting the sample, there is no need to
perform water cooling on the excitation stage, and continuous
analysis of the sample can also achieve better data.
9. The measurement and control system adopts the measurement and
control of the single board machine, and exchanges data with the
host computer to improve the running speed.
10. The computer software is used to adjust the negative voltage of
the photomultiplier tube of each channel, and the negative voltage
of the channel is adjusted by 8 steps, thereby greatly improving
the utilization of the channel and analyzing the optimal linear
range of the spectral line in the analysis of different materials.
Reduce the number of channels used and reduce costs.
11, can be used for a variety of matrix analysis: Fe, Co, Cu, Ni,
Al, Pb, Mg, Zn, Sn and so on.
12, using the operating software under the pure Chinese Windows
system, the operation is simple and easy to understand.
13. The computer software has a database system, which is
convenient for querying and printing measurement data, and can also
transmit data remotely through the network, which is convenient and
quick.
14. Each system is independently powered and composed of units,
which is easy to use and easy to maintain.
15. The optical part constant temperature measure is used to ensure
the normal operation of the instrument, thus reducing the
environmental requirements.
16. High-precision linear motor is used for seam scanning, which is
fast and accurate.
17. Use the overall exit slit to increase the channel.
