Abstract

Inductively coupled plasma mass spectrometry (ICP-MS) is one of the fastest growing fields in analytical chemistry. This discipline combines the powerful detection of mass spectrometry (MS) with the almost universal ionization capabilities of the inductively coupled plasma (ICP) . Combing these two techniques is not a trivial matter, since ions must be extracted from a plasma operating at atmospheric pressures and at temperatures ranging from 6,000­ to 10,000­ C into a mass spectrometer which operates at vacuum pressures(10 -10 torr). At present the ICP and -3 -6 the MS are typically interfaced with a series of two cones. The first is placed in the plasma itself and the second a short distance behind it. This arrangement, combined with differential vacuum pumping, creates a beam of charged particles and ions traveling into the mass spectrometer at supersonic speeds, which is subsequently analyzed.
