Inductively coupled plasma mass spectrometers (ICP/MS);

Glow discharge mass spectrometers (GDMS);

Thermal ionisation mass spectrometers (TIMS);

Electron bombardment mass spectrometers having both of the following features: 1. A molecular beam inlet system that injects a collimated beam of analyte molecules into a region of the ion source where the molecules are ionised by an electron beam; and 2. One or more ‘cold traps’ that can be cooled to a temperature of 193 K (– 80 °C);

Not used;

Mass spectrometers equipped with a microfluorination ion source designed for actinides or actinide fluorides.
