5 Interface Region Chapter 5 takes a look at the interface region, which is probably the most critical area of the entire ICP-MS system. It gave the early pioneers of the technique the most problems to overcome. Although we take all the benefits of ICP-MS for granted, the process of taking a liquid sample and generating an aerosol that is suitable for ionization in the plasma and then sampling a representative number of analyte ions, transporting them through the interface, focusing them via the ion optics into the mass spectrometer, and finally ending up with detection and conversion to an electronic signal is not a trivial task.
2003–2012. All rights reserved. 12 A cyclonic spray chamber (shown with a concentric nebulizer). (From S. A. Beres, P. H. Bruckner, and E. R. ) The cyclonic spray chamber is growing in popularity, particularly as its potential is getting realized in more and more application areas. Just as there is a wide selection of nebulizers available for different applications, there is also a wide choice of customized cyclonic spray chambers manufactured from glass, quartz, and different polymer materials.
As it travels through the different heating zones of the plasma torch, it is dried, vaporized, atomized, and ionized. During this time, the sample is transformed from a liquid aerosol to solid particles and then into a gas. When it finally arrives at the analytical zone of the plasma, at approximately 6000–7000 K, it exists as ground-state atoms and ions, representing the elemental composition of the sample. The excitation of the outer electron of a ground-state atom to produce wavelengthspecific photons of light is the fundamental basis of atomic emission.
