Inductively Coupled Plasma Atomic Emission Spectroscopy (ICP-AES)

The full name of ICP-AES is Inductively Coupled Plasma-Atomic Emission Spectrometry, also known as Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES). It is mainly used for qualitative and quantitative analysis of inorganic elements, and can analyze more than 70 elements in the periodic table. The powerful quantitative function of ICP-AES is widely used in the analysis of sample elements. The fields involved include catalysis, energy, chemical industry, biology, geology, environmental protection, medicine, food, metallurgy, agriculture, etc. As a professional reliability third-party testing organization, T,C&A Lab's Testing Technique can perform ingredients analysis for raw materials and products according to ISO, ASTM and other standards as well as industry requirements. Welcome to contact our experts for consultation.

Qualitative and quantitative analysis of ICP-AES

  • Qualitative analysis

Qualitative analysis is performed by the position (wavelength) of the characteristic spectral lines. Since the characteristic emission lines of each element are different, the existence of the element in the sample can be determined by the existence of several characteristic lines.

  • Quantitative analysis

Quantification is carried out by the intensity of the characteristic spectral lines, and the quantitative analysis generally adopts the standard curve method.

Application range

  • Macro-analysis (0.X%-20%)

  • Micro analysis (0.00X%-0.X%)

  • Trace analysis (0.0000X-0.000X%, generally requires separation and enrichment)

  • Not suitable for measuring more than 30%, the accuracy is difficult to meet the requirements

Sample requirements

  • In general, ICP-AES tests liquid samples.

  • The tested sample must be clear, and particles and suspended matter may block the interface or channel of the inner chamber.

  • The solution sample should not contain components that are harmful to the instrument (such as HF and strong alkali, etc.).
