Domestic ICP mass spectrometer

The iQuad 2300 domestic ICP mass spectrometer is a powerful analytical instrument with wide applications in the fields of chemistry and biology. The advantage lies in its high sensitivity, high resolution, and high accuracy, which can simultaneously determine multiple elements, and it is easy to operate and highly automated.

I. Overview

The ICP mass spectrometer combines inductively coupled plasma (ICP) technology and mass spectrometry analysis technology. In the ICP section, the high-frequency radio frequency signal applied to the inductor coil forms a high-temperature plasma, causing the analyzed sample to evaporate, decompose, excite, and ionize in the central region of the plasma torch. During this process, the elements in the sample are ionized to form ions. Subsequently, these ions were effectively transferred to the mass spectrometry section through the interface of the mass spectrometer.

The mass spectrometry section is a mass screening and analyzer. It is based on the principle that charged particles can deflect in an electromagnetic field. By selecting ions with different nucleation ratios (m/z), it detects the intensity of a certain ion and analyzes and calculates the intensity of a certain element. This analysis method enables ICP mass spectrometer to accurately detect and analyze the elemental composition in samples.

2、 Technical indicators and functions

ICP mass spectrometer has multiple technical indicators, such as mass number range, collision cell design, gas type used, detector type, and dynamic range. These indicators collectively determine the performance and application range of the instrument.

In terms of functionality, ICP mass spectrometer is mainly used for separating and detecting substance composition. It can perform precise analysis based on the mass differences of material atoms, molecules, or molecular fragments. In addition, ICP mass spectrometer also has the advantages of analyzing a wide range of element types, rapidly obtaining isotope information, low detection limit, fast analysis speed, and wide linear range. This makes it have broad application prospects in fields such as chemistry, biology, and environmental science.
