Advantages Together With Disadvantages Of Emission Spectroscopy

Advantages of Emission Spectroscopy.

The emission method is extremely of import inward analysis.

1. The technique is highly specific.
2. The method is extremely sensitive. With this method, every metallic element chemical percentage tin hold upwards detected fifty-fifty if they are nowadays inward really depression focus (0.0001%)
3. Even metalloids (Arsenicum, silicon together with selenium) stimulate got been identified past times this technique.
4. The analysis tin hold upwards performed either inward a corporation or liquid solid soil amongst well-nigh equal convenience.
5. The technique requires minimum sample preparation, equally a sample tin hold upwards straight introduced into the arc or spark.


6. The sample requires no preliminary handling together with tin hold upwards analyzed equally received.
7. Spectra tin hold upwards taken simultaneously for to a greater extent than than 2 elements. No separation is required. A little mensurate of the exam (1-10 mg) is sufficient for analysis.
8. The technique provides results really rapidly. If automated, the fourth dimension required is only xxx seconds to 1 minute.
9. This method has been used for a broad diversity of samples similar metals, alloys, paints, geological specimens, together with forensic material, environmental together with biological samples.
10. The technique permits non-destructive analysis.

Disadvantages of Emission Spectroscopy.

1. The equipment is costly together with broad sense is required for its successful handling together with interpretation of spectra.
2. The recording is done on a photographic plate which sets aside roughly chance to create, impress together with translate the result.
3. Radiation intensities are non ever reproducible.
4. Relative mistake exceeds 1 to 2 %.
5. The accuracy together with precision are non high.
