What is inductively coupled plasma, and the invention history of inductively coupled plasma 2

 High temperature: The temperature of ICP plasma can exceed 10,000 K, which facilitates the excitation of atoms and ions in the sample.

- High energy: ICP plasma can provide sufficient energy to ionize and excite elements, which is beneficial for improving analytical sensitivity and accuracy.diode

- Low background interference: ICP plasma eliminates potential background interference present in traditional flame-based plasma sources, making it suitable for analyzing complex samples.diode

3. Applications of ICP Plasma in Various Fields:

Mass spectrometry: ICP-MS (Inductively Coupled Plasma Mass Spectrometry) is currently one of the most widely used applications, enabling highly sensitive detection of various elements in samples.

- Spectral Analysis: ICP spectral analysis can quickly and accurately determine the content and composition of elements in samples, widely applied in fields such as geology, environmental science, and biochemistry.diode

Surface treatment: ICP plasma can be used in surface treatment processes such as cleaning and modification to enhance material surface properties.diode

The basic components of ICP include the induction coil, gas supply system, spray chamber for loading samples, carrier gas inlet, and detection system responsible for signal acquisition. The induction coil generates a strong electromagnetic field through high-frequency alternating current, exciting atoms or molecules in the gas to form plasma. ICP typically operates at high temperatures ranging from several thousand to tens of thousands of Kelvin, offering advantages such as high ion concentration, low background interference, and excellent sensitivity.diode
