Full spectrum ICP mass spectrometer

The full spectrum ICP mass spectrometer is an advanced analytical instrument based on plasma mass spectrometry technology, which can detect extremely low concentrations of elements. The detection limit of most elements is below the ppt level, meeting the precise detection requirements for trace elements.

I. Overview

Full spectrum ICP mass spectrometer is an advanced analytical instrument based on plasma mass spectrometry technology, mainly based on the principle that charged particles can deflect in electromagnetic fields. When the sample is introduced into the plasma, the elements in the sample are ionized in a high-temperature, high ionization environment. When these ions are accelerated by an electric field and pass through a magnetic field, they will deflect at different angles based on their mass differences. By detecting the deflection angle of these ions, a mass spectrometer can determine the mass of the ions and thus determine the type and content of elements in the sample.
