Thermo Fisher Scientific iCAP Q Operating Manual (P/N 1288090, Revision B) 3-7
Interface
The interface is the region where ions generated in the plasma are
transferred from atmospheric pressure to the vacuum region and
introduced to the mass spectrometer as an ion beam.
The interface comprises the sample cone, the skimmer cone, and the
extraction lens. The cones and the extraction lens are held in the
interface block, which is mounted to the plasma door. The interface
region is water-cooled because of the intense heat of the plasma.
Sample Cone and Skimmer Cone
The sample cone and the skimmer cone are located at the right side of
the interface. The sample cone introduces ions from the plasma into the
first vacuum stage (interface vacuum) and the skimmer cone admits the
ions in the mass spectrometer.
