Simple approach to reducing polyatomic ion interferences on arsenic and selenium in inductively coupled plasma mass spectrometry
Abstract
The addition of small amounts of an organic solvent (e.g., propanol) or a molecular gas (e.g., nitrogen or oxygen) is shown to reduce the interferences on arsenic and selenium of polyatomic ions (ArCl+, Ar2+) at masses 75, 77 and 78 in inductively coupled plasma mass spectrometry.
