DF-67XX Series Laser Elemental Analyzer


Laser induced breakdown spectroscopy (LIBS) is a component analysis technique based on atomic emission spectra and laser plasma emission spectra.

DFMC has 4 type products and measuring way as below:

1.By-pass measurement

It is suitable for measuring point where the material is mixed unevenly,such as the particle size over 30mm,the batching process, is necessary to increase the sampler and crush the shrinkage to less than 13mm,and the best measurement particle size is 3mm.


2.Cross-Belt measurement

It is suitable for measuring point where material are homogeneous mixed,such as sintered material mixture,iron ore,iron concentration,copper ore,copper concentration,etc.


3.Benchtop measurement

Suitable for laboratory applications, it can replace chemical reagents for fast measurement, Alternative to X-fluorescence analysis (S and other elements below 20 cannot be measured).


4.Slurry measurement

Suitable for slurry material inspection, measured by single or multi-channel drainage. For example, iron ore slurry, copper ore slurry. The best materials are solutions, such as bauxite slurry, phosphate slurry, electrolytic aluminum, copper sulfate solution, molten steel, etc.



1.Non - contact fast detection mode, include offline, online, by-pass detection;

2.The equipment uses type IV laser as excitation source, no radioactivity, excellent safety;

3.It can realize the detection of the main elements in the material detection(metal, non-metal);

4.It can realize different forms material detection (solid, liquid, gas) ;

5.It can realize quantitative, semi-quantitative and PPM content element detection.
