Product Description
Ps-sdb410 full spectrum direct reading spectrometer
1. Working principle and Application
Ps-sdb410 full spectrum direct reading spectrometer is composed of excitation module, optical path system, CCD detection system and analysis software. Instrument work
Under the protection of argon environment, the high-voltage discharge generated by the excitation light source transfers energy to the metal material, so that the metal material changes from solid state to gas
State. The outer electrons of the atoms of metal vapor transition from the ground state to the excited state, and the atoms in the excited state are unstable
When it returns to the ground state, the energy is released in the form of light. Different elements emit light of different wavelengths, and the full spectrum is collected by optical path system and CCD detector
The spectrum is solved by the analysis software, the existence of an element is confirmed according to the wavelength of light, and the content of this element is determined according to the intensity of the wavelength
Less.
Ps-sdb410 full spectrum direct reading spectrometer is mainly used to measure the composition of alloy elements and the content of impurity elements in metal materials. It is widely used in metallurgy
Pre furnace inspection, incoming material inspection, quality control and ex factory inspection in gold, casting, machining and other industries.
The measurement accuracy of ps-sdb410 full spectrum direct reading spectrometer is much higher than the national standard. Since it was launched into the market, it has accumulated rich application experience and obtained good results
Recognized by many well-known customers.
2. Technical parameters
Optical structure: ps-sdb410 adopts Paschen Runge structure and Roland circle device to reduce the change of instrument with ambient temperature and vacuum
The influence of stress release caused by change improves the accuracy and stability of the instrument.

Optical focal length: the grating radius is 400mm, and the longer focal length provides excellent resolution for the instrument.
Spectral line range: detectable wavelength range (120 ~ 800) nm, including N, Li, Na, K and other elements and conventional elements,
Meet the requirements of various matrix materials for test elements.
Incident slit: slit width 12 μ m. The fine incident slit can effectively filter out unnecessary stray light and avoid excessive light intensity received by the detector
At saturation, the light intensity interference value between elements is reduced.
Light source lens: MgF2 transition layer made of quartz glass is adopted to ensure the strongest transmission light intensity of ultraviolet wavelengths such as C, s, P and N, so as to make ultraviolet short wave
The measurement results are more reliable.
Detector: CCD detector is adopted, with a maximum of 16 CCDs installed. The layout is staggered up and down, and there is no gap between different wavelengths to make the light
The spectral wavelength is integrated to achieve full spectrum coverage and meet customers' requirements for multi-element testing.
Concave grating: 2400gr / mm, reciprocal dispersion rate: 0.47nm/mm(
Level 1), concave grating can reduce the absorption phenomenon, and there is only light
The light loss reflected by the grid surface at one time, and there is no color difference, so as to improve the effect of vacuum UV spectrum.
Analysis time: it varies according to the type of sample. Generally, one analysis takes less than 40 seconds.
Excitation light source: digital excitation light source with adjustable excitation conditions to meet the analysis needs of different materials.
Metering method: V-F method
Control system: FPGA technology is used to control the working state of the instrument.
Size: 890 * 560 * 515 mm
Excitation electrode: high purity tungsten electrode is adopted. High purity tungsten electrode has the advantages of high strength, corrosion resistance and high temperature oxidation resistance
The influence of instrument parameters on test data in the process of using.
Instrument weight: About 60kg;
Power consumption: 1.0kw;
Vacuum requirement: 5 ~ 12 Pa;
Argon module: analysis flow: 4 L / min; Standby flow: 0.1 L / min;
Excellent argon saving technology: ensure the reduction of customers' demand for argon in daily use and reduce the use cost of enterprises.
Intelligent and advanced gas path monitoring: before excitation, the monitoring system ensures that the sample clamp, sample and spark table form a loop to ensure the tightness of the spark chamber
Sealing and no air leakage. Ensure that the surface flatness of the sample meets the requirements. After excitation, pulse argon purging can improve the dust removal effect and ensure
The short-term and long-term stability of the instrument.
Operating system: brand computer with more reliable quality is adopted, and the operating software system owindlab independently developed by Aowen company is installed, which is unique
The calculation algorithm combined with excellent hardware system greatly improves the performance of the instrument.
