Instrument functions

TH2700Helium plasma emission spectroscopy analysis moduleCan be installed on gas chromatography analyzers as detectors for chromatographic analysis, used for quantitative analysis of various gas component concentrations. Due to the high sensitivity of the analysis module, it is suitable for analysis in different concentration ranges, especially for trace or trace gas analysis, and makes chromatographic analysis more convenient and accurate.

working principle

The analysis module uses a high-frequency and high-voltage power supply to ionize the gas, generating positively charged ions and free electrons, forming a plasma environment. Under the action of an electric field, positively charged ions and free electrons accelerate towards the negative and positive electrodes, respectively. Due to collisions, ions and electrons transfer their own energy to atoms, causing gaseous atoms to be excited. After an atom is excited, its outer electrons undergo energy level transitions and emit characteristic spectra upon returning to the ground state. By detecting characteristic spectra, the concentrations of various gas components can be analyzed.
