ICP-OES stands for Inductively Coupled Plasma Optical Emission Spectrometer.

1、 Working principle
Using inductively coupled plasma as the excitation light source, the sample is atomized and brought into the plasma torch by a carrier gas, where it is evaporated, dissociated, excited, and ionized. Different atoms or ions of different elements emit characteristic spectra during the excitation process. These characteristic spectra are separated into spectral lines of different wavelengths by a spectroscopic system, and the intensity of specific wavelength spectral lines is detected by a detector to determine the content of each element in the sample.
2、 Main features
Simultaneous analysis of multiple elements: Multiple elements can be measured simultaneously, greatly improving analysis efficiency.
Fast analysis speed: able to complete the analysis of a large number of samples in a short period of time.
High sensitivity: It has high sensitivity for detecting low content elements.
Wide linear range: can cover the determination of elements in a large concentration range.
High accuracy and precision: The analysis results are accurate and reliable, with good repeatability.
3、 Application Fields
Environmental monitoring: used to analyze the metal element content in environmental samples such as water, soil, and atmosphere, and evaluate environmental quality.
Geological exploration: Analyzing the elemental composition of geological samples such as rocks and minerals to provide a basis for mineral resource exploration.
Metallurgical industry: detecting impurity elements in metal materials and controlling product quality.
Food analysis: Determine the nutritional elements and harmful substances in food to ensure food safety.
Pharmaceutical field: Analyze the metal element content in drugs to ensure drug quality.
