The characteristics of the OBLF spectrometer

1. The optical chamber having shockproof device, and a thermostatic device.
Light room temperature 35 ± 0.2 ℃, all devices are enclosed in a vacuum chamber, to ensure it’s long-term stability . Even in a poor working environment, the instrument can work normally. The result that all channel with long-term stability shows that there have 300 measurements within eight hours (each ten get an average value), then the 30 average values of the maximum and minimum values are less than the original intensity of 2% ratio .
2. type 1000 adopted with focal length of 500mm concave grating, type 750 with focal length of 750mm concave grating。According to the analysis of sampling grating, to ensure there has sufficient resolution to meet the analysis of complex alloy steel.Concave grating spectroradiometer can not only simplify  the structure,but also improves its performance.

3. Due to the spectrometer was in working day and night, using computer control of vacuum pump, thereby not only ensuring the enough vacuum but also protecting the vacuum pump, make it in cold state to prolong the service life, reduce oil vapor.

4. Improve the analytical sensitivity and accuracy, the optical path of the direct type light intensity is enhanced, and use pulse discharge to excited light source, the discharge frequency up to 1000 Hz and single spark technology, which can greatly improve the signal-to-noise ratio and excitation stability, which has a good analysis precision.
5. The good performance of the spectrometer software, make the instrument fully automated and can carry out the background correction, correction of interference elements, matrix correction, in order to ensure the accuracy of analysis.

Because the above characteristics the OBLF spectrometer with, so that the apparatus can meet the rapid analysis requirements of foundry industry furnace, so now are widely used in the majority of casting, metallurgy, machinery and other industries.
