Advantages of ICP-AES method:

The wide applicability of ICP-AES in the quantitative analysis of various materials can be attributed to the following advantages.

• Rapid and concurrent multi-element analysis.
• Lack of chemical interferences.
• High temperature of the excitation source: 5000 to 10000K.
• Low sample requirements.
• Absence of self absorption, a cause of non-linear calibration plots in FES.
• Validity of calibration curves over 4 to 6 sequence of magnitude.
• Low detection limits: 1 to 100 ng/g or µg/l (part per billion).
• Good accuracy and precision: that is relative standard deviation of about 1 percent.
• Applicability to components that are difficult to be determined by AAS: B, C, Ce, La, Nb, Pr, S, P, Ti, Ta, V and Zr can also be measured.
