Technical characteristics of CCD spark Optical Emission Spectrometer


Innovative optical system and extended wavelength range can ensure accurate identification and trace analysis of important elements. The instrument has extremely low detection limits and excellent long-term stability. The analysis results are accurate and reproducible.  The combination of advanced CCD detector and digital readout technology makes the overall design of the instrument superior to the traditional photomultiplier tube technology, and has gradually become an important choice for the metal manufacturing, processing and foundry industries.


1. Compared with the traditional photomultiplier tube technology, the new optical system design is more accurate and stable in element identification and analysis.  

2.CCD solid-state detector technology, the latest grating spectroscopic technology.  Since the vacuum spectroscopic system uses multiple linear array CCDs as the detector, it has up to 2400x8 pixels and realizes full-spectrum reception in the analysis band.  

3. Unique light room placement.  Aiming at the observation characteristics of the plasma spectrum signal, in order to obtain the best observation angle to obtain the best analysis data, placed the light chamber at a specific angle.

4. The loaded vacuum system works through the latest generation of vacuum pumps and is equipped with a safety solenoid valve to maximize the safety of the vacuum system.  

5. New spark table design. The spark table adopts a sealed design. In addition to retaining the advantages of the traditional spark table, it has been optimized accordingly for new application requirements.  Keep the structure of the spark table stable when the instrument is continuously excited by high temperature sparks.  The structural design of the spark table has also improved the injection direction of the argon gas stream, greatly reducing the residue of spark-excited residues on the spark table, and at the same time, it makes the cleaning and maintenance of the spark table easier.  

6. The design of the open sample stage makes sample placement and analysis easier, and sample processing is simpler than traditional spectroscopy.  The sample stage does not need to be sealed, and small samples such as wires can also be conveniently analyzed and pulled by the adapter to pull the front cover, which makes the cleaning and maintenance of the excitation stage more convenient.  

7. Unique Jet Electrode Technology , in the excited state, an argon gas jet will be formed around the electrode, this technology also has many advantages; the argon gas around the excitation point ensures that the excitation process is not affected by external interference, saving the use of argon gas reduces the cost of use for customers.  

8. Synchronous real-time digital readout technology. Compared with the traditional sequential readout technology, the analysis time and data stability will be greatly improved.  

9. All-digital plasma spark light source technology.  All excitation parameters can be customized by the user through the user interface according to actual needs.  

10. The circuit system is completely separated from the optical system, and the circuit system is uniformly placed on the outer part of the instrument's light chamber. This design greatly improves the heat dissipation function of the instrument and facilitates subsequent maintenance of the instrument.  

11. Simple and convenient operation software,English menu. Operators without any knowledge of spectroscopy instruments need only simple training to use the instrument.  At the same time, the design of the instrument embodies the human-oriented design concept, making the use and maintenance of the instrument embody humane care.
