WebMay 4, 2024 · The vertical axis represents the relative intensity or signal of the ions detected in the mass spectrometer, while the horizontal axis represents their m/z ratio (the mass divided by charge number). The strongest peak will therefore have a relative intensity of 100. Pentane has the chemical formula C 5 H 12. WebCommercial ICP-MS instruments use a CRC containing a multipole ion guide, either a quadrupole (4 rods or poles), hexapole (6 rods) or octopole (8 rods). Quadrupoles permit mass-selective rejection of ions (e.g. reaction product ions or precursors to interfering polyatomics), using a user-selected bandpass window.
