Mass is a characteristic property of every element and serves for qualitative, as well as quantitative, analysis. Besides, it is possible to determine the isotope ratio. Restrictions often arise with an ICP MS by background noise that is specific for the device, as well as by interferences of the system.

ICP / MS
ICP MS is the abbreviation for inductively coupled plasma mass spectrometry. A great number of elements, including their isotopes, can be determined by this analysis method in quite a short time. Because of the extremely high detection level, ICP MS is one of the most frequently used processes in trace elemental analysis.Architecture of an ICP MS
An ICP MS consists of a sample introduction device, an excitation source, the so-called inductively coupled plasma, a separation system, the mass spectrometer, and a detector, an electron multiplier.Functionality of an ICP MS
The liquid samples are introduced with the help of a nebuliser into the inductively coupled plasma. The nebuliser generates fine aerosol of a homogeneous droplet ratio and low droplet size. The charged particles are generated by ionisation in the induction coil of a high frequency generator. Generally, argon gas is used which can easily be ionised. The generated aerosol is evaporated at a temperature of approx. 6000 °C, then atomised and ionised. The resulting ions are separated in a mass analyser. There, the ions are extracted from the normal pressure area into the high-vacuum area. The mass analyser consists of four parallel metal rods. These are arranged in equal distances around an axis. A direct current is applied to these metal rods, separating the ions by the mass-to-charge ratio. Ions leaving the mass analyser are detected by an electron multiplier. Negative voltage is applied to the input of the electron multiplier, attracting the positive ions. The ions thus hit the electron multiplier that is coated with metal oxide, knocking out secondary electrons. At the end of the electron multiplier, the electrons are detected as a signal.Mass is a characteristic property of every element and serves for qualitative, as well as quantitative, analysis. Besides, it is possible to determine the isotope ratio. Restrictions often arise with an ICP MS by background noise that is specific for the device, as well as by interferences of the system.
