  • Desktop Spectrophotometer CS-800 for Tombar Thite Color Measurement

  • Tombar Thite (Rare earth) has the laudatory title of industrial vitamin. Now it has become an extremely important strategic resources. Rare earth element oxides refer to 15 elements of the periodic table of atomic number 57 to 71 of lanthanide oxides, and lanthanides similar chemical properties of scandium (Sc) and yttrium (Y) a total of 17 elements of the oxide . Rare earth elements in the petroleum, chemical, metallurgy, textile, ceramics, glass, permanent magnet materials and other fields have been widely used, with the progress of technology and application technology breakthroughs, rare earth oxides value will be more and more.

    So the enterprise pays more and more attention on color difference of rare earth. The general human eye observation error will be relatively large, so most companies are more inclined to the use of color measurement equipment. Today we use our CS-800 desktop spectral color measurement instrument to tell you how to measure the color of rare earth.

    CS-800 desktop spectrophotometer adopts D/8 illumination observation geometry and its testing caliber is upward which is more convenient to measure solid materials, pellets, powder materials and pasty materials.
    Solid samples (steel plate, clothes) could be put on the testing caliber directly. Pellets (tablets, color master batches), powders(pigments, coffee) and pasty materials (tomato source) can be put in cuvette and then put on the testing caliber.
    Step 1. Prepare the target and testing samples. Weight the samples by electronic balance with equal weight, to prevent the measurement error caused by different weights(as shows in figure).

    Step 2.Turn on the desk top spectrophotometer CS-800 and then calibrate it (as show in figure).

    Step 3.Press the rare earth into pellet by jack. Because powder rare earth will cause light-leaking situation. Pressing into pellets will avoid the measurement error.

    Step 4. After calibration, press “cancel” to exit and then put target sample on the testing caliber, then press “test”, after hearing the sound of “beep”, we could see the target sample testing result on the screen.

    Step 5. After the standard measurement is completed, press the "Menu" button, you can enter the standard sample under the "sample measurement" interface. Put the testing sample on the testing caliber, press “test” for measurement, after hearing the sound of “beep” we could see the testing result.

    According to the testing result, customer could see the color of rare earth directly, and color difference value is also on the screen. Comparing with visual method, spectrophotometer has the advantage of objectivity, simple and fast operation, high repeatability precision,etc. time saving, labor cost saving and improving efficiency.
